2/26/2010 - Five indicators to measure battery performance

There five indicators to measure battery performance

Secondary batteries is known as rechargeable batteries or battery,such as    en-el4   battery ,measuring the performance mainly depends on secondary battery voltage, capacity, energy, power, cycle life of these five areas.

Voltage including charge and discharge the battery in the theory, the working battery voltage, battery charge voltage and battery termination voltage. theoretical discharge voltage and the theoretical charge voltage is same ,and they are equal to the battery open circuit voltage,like the    li-12b battery.

The battery voltage is the actual battery discharge voltage ,it is relevant with the battery discharge method, using temperature, charge and discharge times and others(it also includes whether it is famous battery,such as    inspiron 1520 battery  or not ) .The battery charging voltage is greater than open-circuit voltage, the greater charge current is ,the voltage higher , the greater the battery heat ,the temperature of the battery during charging higher.

Termination of the battery voltage is that the the voltage of battery is not appropriate to continue to discharge down to the minimum operating voltage in the discharge process,.

Battery capacity refers to a certain discharge conditions, you can get electricity from the battery, that battery can release energy. Battery capacity is divided into theoretical capacity, practical capacity. The battery's theoretical capacity is calculated in accordance with the electrochemical reaction from the capacity. Actual capacity refers to a certain discharge conditions, the battery can release the actual amount of power,for one thing,the Dell   inspiron 6000 battery .

The battery capacity is defined as more than a certain discharge conditions,obtained battery power from the unit mass (volume) , that is,the battery can release energy.

The energy of the battery is the output of electricity can do work outside in certain discharging conditions , As the active substance can not be fully exploited, and the battery voltage is always less than the electromotive force, take the inspiron 6400   akku ,so the actual energy of the battery is always less than the theoretical energy.

The battery specific energy (energy density) is the output energy of unit mass (volume) batteries , namely, the volume ratio energyor the mass ratio energy. the actual output energy is the energy of the battery ratio battery quality (weight) or volume .

The     en-el8 battery power is the battery power battery output  per unit time in a certain discharge conditions, unit is for the W or kW. Battery power is the power unit mass (volume) cand output ,the unit is for the W / kg or W / l.

2/26/2010 - Zinc-manganese batteries Introduction

Zinc - manganese dioxide dry battery (zinc-manganese dry battery) referred to as zinc-manganese batteries, take the Canon   lp-e5  battery for example , manganese dioxide is used as cathode active material, the original battery use zinc negative electrode as active material. Cells using ammonium chloride and zinc chloride or potassium hydroxide in aqueous solution as electrolyte, surface starch, film coated paper or special paper is used as isolation layer, usually made of gel or electrolyte solution absorbed in the isolation layer, vector, was not flowing state, so called dry. Zinc-manganese battery nominal voltage of 1.5 volts.such as the    nb-3l battery. Electrolyte solution  are divided into thress types by the use of different types ammonium chloride ,such as ammonium chloride, zinc chloride and alkaline. Ammonium chloride and zinc chloride-type zinc-manganese battery manganese battery is known as the neutral (or carbon-zinc batteries, carbon zinc batteries).

Zinc-manganese batteries  is divided into cylindrical shape (with "R" indicated) and non-cylindrical battery (with "P" indicated) two kinds,according to their size and electrochemical system named after the  Fujifilm   np-100 battery,. However,  prior toOctober 1990,a non-cylindrical-shaped battery is divided into shut-ping (using the "F" indicated) and side (moment) form (with "S" indicated). Dimensions mentioned here do not mean a whole cell (battery) form factor, but  one of the single cell (cell) form factor. For example, the battery 6LR61 the overall shape is square (moment) form, but that one of the single cell LR61 is cylindrical, so the battery model is based on the shape of single cells "R" named. Shut by several cells in series flat-shaped zinc-manganese composite made of single cells, often referred to as stacked-type battery.

Neutral zinc-manganese batteries can be divided into cardboard paste-type cells and batteries,for one thing ,the    np-40 battery .according to the difference between isolation layer ; according to the level of battery capacity,they also can be divided into ordinary products (S), high-capacity (C) and high-power (P) 3 grades, but the recent IEC standard battery has been canceled C-, neutral zinc-manganese battery-free electrochemical system code. Alkaline zinc-manganese batteries combined in form and pre-electrochemical system, code-named code-named "L" said.

Zinc-manganese battery is the oldest of the original battery for vgp-bps2a . the battery is still the leading civilian products. With the continuous development of science and technology, neutral, alkaline zinc-manganese batteries will gradually be replaced by zinc-manganese batteries. when the IEC standard is currently changed ,the battery C-type was removed  .

2/26/2010 - Common fuel cells

Here are five kinds of fuel cells :

Proton exchange membrane fuel cell (PEMFC)

the electrolyte of Proton exchange membrane fuel cell(like the Jvc bn-v408 battery)is a thin polymer membrane in the proton exchange membrane fuel cell,such as poly [perfluoro sulfonyl] acid (poly [perfluorosulphonic] acid), and protons can penetrate, but not conductive NafionTM , while the electrode is composed of basically carbon. Hydrogen go into the fuel cell to reach the anode,and cracked into hydrogen ions (protons) and electrons from the sb-l160 battery . Hydrogen ions go into the cathode through the electrolyte penetration, while the electrons flow through an external network to provide electricity. At the same time, to form the air of oxygen for supplying the cathode, and combine with electrons and hydrogen ions to form water.

Alkaline fuel cell (AFC)

Phosphoric acid fuel cell (PAFC)

Such cells use liquid phosphoric acid as the electrolyte, the operating temperature is slightly higher than the proton exchange membrane fuel cells and alkaline fuel cell operating temperature, it is 150 ~ 200 ℃ or so, but still rely on the platinum electrode catalyst to speed up the reaction. The anode and cathode reactions and proton exchange membrane fuel cell is same, but because of its higher operating temperature, so its reaction is faster than proton exchange membrane fuel cell cathode speed on the cathode ,take the Samsung sb-l110 battery for example .

Molten carbonate fuel cell (MCFC)

Molten carbonate fuel cell (for one thing ,the sb-lsm80 battery )uses a molten lithium-potassium carbonate or lithium sodium carbonate as the electrolyte. When the temperature is heated to 650 ℃, this salt will melt, producing carbonate ions, flow from the cathode to the anode , and combine with hydrogen produce water, carbon dioxide and electronics. Electronics and then return to the cathode through an external circuit, generating in this process.

Solid oxide fuel cell (SOFC)

Solid oxide fuel cell operating temperature is even higher than the molten carbonate fuel cell temperature, used as solid ceramic electrolyte, such as yttria stabilized zirconia and other solid ceramic electrolyte, instead of using the liquid electrolyte. Its operating temperature is located between 800 ~ 1000 ℃. In such a fuel cell fo inspiron 1501 akku , when the oxygen ion moving from the cathode to the anode, so that oxidation of fuel gas (mainly hydrogen and carbon monoxide mixture)generate energy. Anode return to the cathode to reduce the access of oxygen through the external circuit, thus completing the cycle.

2/26/2010 - Thin film technology solar cell market share will be double in 2013

According to iSuppli Corporation, thin-film solar cells are rapidly capturing the market share that crystal technology have by 2013,such as bp-522 battery . the PV part will be more double than the number of watts. solar panels in the global market, the efficiency of thin film will be from 14% in 2008 to 31% by 2013.

"First Solar has a strong proof of the viability of thin-film market(take the Canon bp-711 battery for example )the company jumped the world's largest manufacturer of solar panels this year, production is more than one billion watts." ISuppli's research director GregSheppard said, "At the same time, the company has already reduced per-watt the cost of production down to less than 90 cents a silicon crysta,it l is about half of the module manufacturer. "

Crystal and thin-film

Most solar panels made from crystalline silicon, using 180-230 micron polysilicon. On the contrary, thin-film panels is made of other materials through the deposition of multi-layer substrate , the thickness is a few microns. The main difference between the two technologies lies in the efficiency and cost of electricity per watt. when thin-film panel convert the sunlight into electricity,the efficience is lower , but its production costs are significantly lower,like the Canon bp-911 battery.

It is noteworthy that the film have a disadvantage in the limited installation space , such as residential roofing. Film installation may need more space to account for 15-40% of the crystalline silicon to achieve the same with the overall system power output. This tends to limit its activities in certain application areas more attractive.
Price comparison

Thin-film modules are expected next year, the average price will drop to 1.40 U.S. dollars, it is lower than in 2009 for 1.70 dollars ,such as Jvc bn-v408 battery .In 2010 the average price of crystalline silicon panels are expected to fall to 2.00 dollars, 2.50 U.S. dollars this year.

iSuppli Corporation predicts that crystalline silicon will narrow the price gap to a certain extent by 2012 , because its suppliers are financially strong, they continue capital expenditures and technology development ,and has invested heavily in improving production processes.

Variety of thin film technology

Most of these techniques rely on chemical vapor deposition (CVD), or derived from the screen printing process, the layers of material deposited on different substrates, namely glass and various plastics. Some of the recent use of inkjet printing technology, like ways to more quickly deposited materials.

Another factor which promote the accelerated development of thin film technology is the use of materials, some companies provide more production lines, such as Oerlikon, and Centrotherm package,and inspiron 1420 akku company.

There are a variety of thin-film photovoltaic technology. They are mostly less than 10% efficiency, although some solar cells for np-f330 technology can be efficient through experiments up to the middle class. Some of these technologies are referred to as a single node, using a diode. Recent developments in the use of multiple nodes with each other superimposed together, also known as tandem and three knots, so by using different materials or combinations wider absorption spectrum of knot.

2/10/2010 - China New Energy Automobile Technology

the new energy vehicles recently frequent  appeared in the major auto show, but in the process of large-scale production, batteries for inspiron 6400 battery , motors and other key components highlight the technological bottlenecks, new energy automotive experience, "Game No One Played" embarrassment.

•   The coexistence of a variety of technical line

  According to China's industrial policy,  the Chinese Society of Automotive Engineers Parts surmised that the Minister for Yan Jian, China's technological development of new energy vehicles for the hybrid power train of thought is the starting point for new energy vehicles, pure electric vehicles for the medium-term objectives, to fuel  Casio   np-100 cells as a long-term.

  Chinese experts said hydrogen-powered fuel Dell   inspiron 8000 battery cell vehicles are considered to be the ideal academic community of new energy vehicles, but because of the current high cost of hydrogen and fuel cell technology, a series of security-related issues remain to be cracked, and therefore can only be is the look "foreign" sigh.

It has been learned so far, China has 24 companies, 47 kinds of new energy automotive products included in the Chinese manufacturing enterprises and product announcements, which includes electric vehicles, hybrids, to electric vehicles based New Energy Auto Industry Base spring up all over the country. In the capital markets, some within the industry chain in electric car batteries for Dell   inspiron 8100 battery  , motors and other enterprises have been sought after.

•   bottlenecks  of the key technical

According to reports, although compared to Japan, Europe and the United States a number of countries, the development of new energy vehicles akku in China starting not later, but the domestic automobile enterprises of new energy technologies are not advanced. The key technical "stuck" so that the new energy automotive industry domestically-oriented enthusiasm hard to get into real productive forces. On the pure electric cars are concerned, lead-acid Dell   inspiron 8200 battery battery life is short, resources of nickel-metal hydride batteries is limited , and  cost is high.

•   old and new Technical problems  exist is in side by side

Automotive Engineering Department of Tsinghua University Professor Ouyang Minggao pointed out that Power Batteryinvolves a hybrid Dell   inspiron 8500m battery powered, pure electric and fuel cell three kinds of electric vehicles, so the transformation of power system will strongly rely on battery technology breakthrough. However, the battery technology is at the present stage of China's industrialization of new energy vehicles, there is the greatest difficulties, including the nickel-metal hydride batteries for Dell   inspiron 8600 battery and lithium battery life, consistency, cost and other aspects. He also said that first of all resistance, currently one of the best level and abroad 10 times the difference between the level of the best. Another problem is the consistency of the battery, lithium batteries have a characteristic, over-charging and over-discharge is not good, such as mobile phones using a single-chip Li-ion battery problem easy to control, but the vehicles use    inspiron 9400 battery  is a complex series-parallel connection in a number of together, if consistency is not good, it is easy to cause some over-charge, some charge less than a phenomenon, which will affect the entire battery life and cost. At home and abroad on this issue have not yet been completely resolved.

In addition, the voltage of theinspiron 9200 battery  electric vehicles are now about 100 volts to 600 volts, when a car fell into the sea accidents, how to maintain the passengers fail to shock, but also need to overcome the current technical difficulties, one of

Many in the industry have pointed out that the traditional car key technical level will largely determine the level of development of hybrid cars . Despite an increase in hybrid electric vehicle motor as power source, but the conventional internal combustion engine continues to play an important role. Thus, in addition to motor Dell   inspiron 9300 battery  and other new technologies should be continuously explored, the enhancement of automatic transmission inherent in the traditional car key technologies as urgent.

2/10/2010 - Photo-thermal hybrid solar cells

Recently, U.S. researchers are jointly developing a tiered solar thermal hybrid solar Dell   vostro 1500 battery  , combine the solar photovoltaic cells and the thermoelectric materials  to absorb light and heat , two different forms of solar energy. Meanwhile, the U.S. Department of Energy is also hoped that the solar cells are made into wooden tiles, in order to contribute to the environment. To achieve this goal, the Department of Energy to the United Engineering Corporation  allocated 150 thousand U.S. dollars of funds to help it for the first phase of research and development.

  The company is currently working with Columbia University in New York. The researchers hope that the roof solar Sharp   md-mt831 battery panels solar thermal hybrid solar  conversion efficiency can reach 12%, although the efficiency is not high, but considering the low cost, is still attractive. At present, models produced: In the solar panels under the outermost layer of protection is a photovoltaic solar cells for Casio   np-100 , followed by the researchers referred to as "functional upgrades sandwich", and from the plastic tube composed of thermoelectric materials. Plastic Header Pipe into the cold water cooling panels to play the role of outflows into the hot water heating for people to use. In the plastic tube below the bottom of the battery plate: plastic strengthened stories. Photovoltaic solar cells to solar electromagnetic radiation into electricity, while the thermal layer of solar thermal energy will be converted into electricity. Researchers presented, plastic pipe "feature upgrades sandwich" in the whole hybrid solar panels plays an important role, especially in the summer, the solar Dell   inspiron 710m battery  temperature is too high, the conversion efficiency becomes low, this time plastic pipe cooling device The role will be very obvious.

  Right now, other than the battery for Dell   inspiron e1705 battery were tested on the laboratory of Columbia University  , they will be tested in New York, Douglas College (FDA) a roof area of 6.4 square meters of construction . The researchers also calculated the cost of the technology to generate electricity, which is determined that a new energy technology can compete with fossil fuels, the most basic standards.

  This are the first stage of the experiment. If the success of this phase, researchers will be 6 months into the second stage: one million U.S. dollars from the Department of Energy to obtain funds in a year the technology was further improved. After the third phase is likely to cost 10 million U.S. dollars for the solar battery , inspiron 7500 battery  technology, commercial production. Some studies presented, and they wanted to end within five years, the technology will go into market.

  U.S. Department of Energy said they were very supportive of the plan. Solar cell for Dell inspiron 7500   series battery has not been able to penetrate into the market, mainly due to the initial high cost, conversion efficiency is low, but the solar thermal hybrid rooftop solar panels are part of the building's surface, and the efficiency has been improved. At the same time, these low-cost, durable   akku panels is extremely suitable for installation in ordinary residential and commercial buildings, the wide range of uses and broad prospects.

2/10/2010 - Battery Type

1. Nickel-cadmium batteries (Ni-Cd)

It is used in laptop batteries for Dell   inspiron 510m battery  in the veteran, but because it has a serious memory effect as well as the anode material used in nickel (Ni) on the environment will be toxic and cause pollution, so it is quickly was despise laptop, and replaced by a more superior nickel-metal hydride batteries.

2. Nickel-metal hydride batteries (Ni-MH)

the structural principle of nickel-metal hydride Dell   inspiron 6000 battery is same with nickel-cadmium batteries , but it  replaced  the cathode by performance better, more environmentally friendly non-toxic  nickel - metal hydride materials. Although only a small change, but it has brought a dramatic increase in performance. It also has an unmatched to make the advantages of nickel-cadmium battery is memory effect was not obvious, so that so that we no longer have the memory effect for that nasty trouble and become more user-friendly. Although the performance of nickel-metal hydride batteries for Dell   inspiron 600m battery  are very good, but with technological advances, it is lighter in weight and a higher energy density lithium batteries replaced, become the laptop battery in the history of deadwood.

3. Li-ion battery

Many people think that lithium Dell   inspiron 630m battery battery means that we are now commonly used in lithium-polymer battery, in fact, lithium batteries, including lithium metal-ion battery (Li-MO2) and lithium-polymer battery (Li-ion) are two. Because Li-MO2 cells to enter the market in 1989, caught fire when the explosion occurred while the die, so it will soon disappear from people's sight, replaced by a safer lithium-polymer battery. It is light weight, in the same capacity under its nickel-metal hydride battery for Dell   inspiron 6400 battery  weighs only about 1 / 2, so it is fast becoming the new darling of mobile portable devices have been used in most notebook computers, is now the backbone of notebook batteries.

4. Fuel Cell (Fuel Cell)

Fuel cells are the future of Dell   inspiron 640m battery star, it has many types, including proton exchange membrane fuel cell (PEM), alkaline fuel cell (AFC) and solid oxide fuel cell (SOFC) and many other However, due to the fuel cell start-up time and operating temperature and other reasons in fact suitable for notebook computer use only the fuel cell proton exchange membrane fuel cell (PEM). PEM fuel cells for Dell   inspiron 700m battery using methanol fuel, from the positive and negative electrodes composed of the principle of its power generation is the result of the methanol, after re-enter the negative hydrogen and oxygen enter the cathode, through the catalyst, hydrogen atoms into protons and electrons, by different paths into the cathode, e-cycle to produce electricity through an internal, proton through the electrolyte to achieve positive, combined with oxygen to produce water and electrical and heat.

The experts agreed that restricting the commercial application of fuel cells, the biggest factor is the fuel Dell   inspiron 700m battery cell to use the metal platinum (Pt) or platinum as catalyst to make the cost of production has been high, the current production cost of the fuel cell 500 ~ 1000 USD / kW. Research shows that only when the fuel cell production costs fell to 50 U.S.dollars / kilowatt level can be truly accepted by consumers. The high cost of fuel cells is mainly due to mass production has not been formed, once entered mass production stage, the price of fuel akku will certainly be greatly reduced.

2/8/2010 - lithium-ion battery

  Mobile phone xps m1530 battery is divided into three major categories on its manufacturing material: nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion battery. One nickel-cadmium batteries are the first generation of mobile phone battery, it is a low capacity, there is memory effect, requires frequent discharge to maintain capacity, and creating materials, there is environmental pollution, the current cell has been basically eliminated. Second-generation high-capacity Ni-MH Fujifilm   NP-95 battery, no memory effect, manufacturing, materials, little environmental pollution, people used to call it environmentally friendly batteries. The current development trend of mobile phone battery is a lithium-ion battery, its advantages are:

1. no memory effect, no discharge, the use of a long time.
2. a high voltage. Usually single lithium-ion battery voltage of 3.6V, Ni-MH, Ni-Cd xps   m1730 battery voltage of 1.2V, a difference of 3 times.
3. small size, light weight, high specific energy. Lithium-ion battery energy density of up to nickel-cadmium batteries two times. Ni-MH battery with the same volume compared to the volume can be reduced by 30%, weight can be reduced by 50%.
4. long life. High-quality lithium-ion
xps   m1330 battery life of up to 1,200 times or more, much higher than other types of batteries.
5. safe and fast charging. Lithium-ion batteries due to use of special technical processing, thereby allowing fast enough within 2 hours of electricity, but also greatly improved safety performance.
6. allows a wide operating temperature range. Lithium-ion battery for Nikon   EN-EL8can work between -20 ℃ -60 ℃. High-temperature discharge performance is superior to other types of batteries.

So how to identify genuine and fake batteries? In the non-professional conditions, can use the following methods: equal-capacity battery, lithium battery  for Nikon   EN-EL1 than the nickel-metal hydride and nickel cadmium batteries feel lighter; dedicated lithium battery charger with the battery charge, if the process of charging the battery heat, then the is a nickel-metal hydride, nickel cadmium batteries, if no major changes in temperature, it is lithium battery; to make the battery positive and negative "instantaneous" short-circuit before use, such as theNikon   EN-EL9 battery, "no power" is a lithium battery, if still "have electricity" is a nickel-metal hydride, nickel cadmium batteries.

The use of lithium batteries should be noted for a period of time ,after the battery is placed it can go into hibernation, lower than normal capacity at this time, use of time has also come to shorten. After 3-5 times rechargeable Olympus   li-40bbattery can be activated to restore normal capacity.

When the battery is inadvertently short-circuit when the internal lithium battery protection circuit will cut off the power supply circuit in order to ensure the safety of users will be out to re-charge the   akku can be restored.

To buy lithium batteries, should choose after-sales service, international, national identity, brand batteries, take the Nikon   EN-EL11 battery for example , such batteries are made of  high quality raw materials, with comprehensive protection circuits, shell beautiful, wearable, with security chip, and with mobile phones with the good can be achieved Good communication results.

2/8/2010 - Battery recycling is a problem

January 21, Chung-tai 2008EV hit the domestic market first mass-produced electric car flags. Also started to manufacture the  Casio   np-100 battery, and has been walking in the forefront of BYD  electric vehicle research and development in china as well. There are indications that new energy vehicles The technical line has been quietly shifting to electric cars, in 2010, new energy vehicles to enter the full "electric shock" era.

•   Environmental protection need a prerequisite

  Energy use up clean, but its manufacturing process is also clean it? At present, China's coal-based energy generation, followed by hydropower, nuclear power a very small proportion. Coal-fired power plants in the production of electricity, the emissions of carbon dioxide from Nikon   en-el3 battery to be much less than the fuel cars. However, the number of electric vehicles soared, the carbon dioxide emissions is still not a small number .

•   Battery recycling is a difficult issue

  As we all know, the  xps m1710 battery contains heavy metals, acid, alkali and other substances. In the usual process of using these substances have been encapsulated in the shell, it will not harm the environment and the human body. But when the battery was abandoned, due to the long-term mechanical or corrosion effects, making batteries and other heavy metals and acid-base leak out, it may cause serious environmental pollution problems. In addition, some after the acquisition of plant acquisition of scrap akku , only a simple removal, whichever is useful to some, but will the rest discarded into the environment. The same may lead to serious environmental pollution. If you can establish a unified recycling system for the regeneration technology is not perfect, or energy-consuming, expensive too large, it is recommended a centralized approach to deep landfill. But the best way is still using reasonable recycling Jvc   bn-vf808 battery technologies to avoid waste of resources.

2/3/2010 - The internal structure of laptop batteries and battery DIY

• The internal structure of laptop   batteries

Notebook computer Dell   inspiron 6400 battery  are generally made of the shell, battery, charge and discharge control and protection circuits (to prevent over-charging and over-discharge), etc..

Talk about  battery pack as a core component of notebook computer   akku . General laptop battery is 10.8V or 11.1V, and a single cell can not meet the requirements of notebook PC batteries and are based on so many single cells in series and parallel component of the battery pack (pictured is the use of two sets of three parallel and in series after the to form a battery group). As we often see in the Sharp   md-mt831 battery  shell of 3300mAh, 4400mAh and so refers to the capacity of the battery, which is indicative of the current on the battery discharge can be used for one hour, for example: 4400mAh lithium battery can discharge current 4400mA for one hour . Therefore, the value the bigger the better to prove it can work longer.

To charge and discharge control and protection  is responsible for the Casio   np-100 battery charge and discharge control and protection, and it works principle is that, because the lithium battery in the charging process is very close to the full voltage will drop slightly 1:00 pm Therefore, this control circuit to detect a situation that when the battery is already full, and protection circuit is also working to cut off power supply in order to prevent overcharging; discharge the battery voltage is basically stable and unchanging, the remaining battery power only rarely, when a sudden drop in only, when the control circuit detect this situation is that the battery for Jvc   bn-vf808 power ran out and inform the protection circuit cut off power supply to prevent excessive discharge the battery life shortened.

Because the current laptop battery prices(such as Dell vostro 1500 battery )are generally not cheap at between 600 to 2,000 yuan, the price can be described as stubbornly high, many often have to use the battery notebook users a headache. In fact, a battery life does not mean the end of the battery completely useless, because the general is just its internal battery pack or failure caused by aging, while the circuit part of the generally intact so long as you are willing to play about the spirit of DIY you can save not little money.

  It can be sure to have a little physical knowledge and bold but cautious ,when you replace battery for Jvc   bn-vf823 pack by yourself , that is to dare to open the battery hands, hands they need to be careful not to damage the circuit or else you do not want to buy some of the new Du Bu Xingle. In fact, this is very simple, in the post-open the battery cover you can see the internal battery pack and circuit, when you carefully look at your Samsung   sb-lsm160 battery pack and parallel mode (what? You do not know how to look.) and the use of battery type, model and number, about these after going to buy back the battery electric market, the battery needed to monomer, and a lithium battery monomer is generally 20 to 35 yuan. Buying the battery monomer should be noted that simply have to buy the same brand, same model, same batch of products, because the experiments show that a number of battery strings in parallel when using the battery for Canon   nb-71,due to subtle differences in monomer monomer will advance to a battery failure thereby affecting the work of the entire battery pack, so be sure to note.

  After  buy   Fujifilm   np-95 battery back,it is necessary to  take off the old battery from the battery group, one by one electric soldering iron down, and then go back to new as is welding, but to remind what is the electric soldering iron temperature should be high, so that the welding process can be used a very short period of time and battery contacts, or a result of high temperature Ershi shortened battery for Jvc   bn-vm200 life and performance. Finally the case with the 502 like the glue seal is good, loaded back on to test if the laptop is no problem, then congratulations you're done!

1/29/2010 - Thin-film battery is an inevitable trend as a market-led

In the August 26, 2009 the State Council executive meeting, due to overcapacity and redundant construction, polycrystalline silicon xps m1710 battery be "named." To replace the polysilicon thin-film industry have increasingly high expectations. An exclusive interview with this newspaper on this issue Oerlikon Solar CEO Juergen • Hans.

 
1. As the world's leading thin-film silicon photovoltaic production equipment supplier, you can talk about the thin-film silicon solar cell for Sony   np-fh100 panels in the global PV market share enjoyed a much Mody?
 

Oerlikon Solar's global production capacity over 450 MW installed capacity of Oerlikon's customers so far has produced more than 1 million solar Jvc   bn-v428 panels. Oerlikon's amorphous silicon and microcrystalline laminated (Micromorph) thin-film silicon solar photovoltaic technology to customers in Germany in early 2008, launched the world's first one Micromorph line.

2. Non / microcrystalline silicon thin-film solar cells of crystalline silicon solar Dell xps   m1730 battery  as opposed to what advantages do? A low conversion rate is the thin-film solar cells a major shortcoming, Oerlikon is how to compensate for this shortcoming it?

First of all, the non-/ microcrystalline silicon thin-film solar cells ,Sony   np-qm71d on the absorptive capacity of visible light stronger than the crystalline silicon. The same power thin-film crystalline silicon solar cells and solar cells compared to the year as a unit, made more electricity. Second, the non-/ microcrystalline silicon thin film solar cell production is silicon prices have little impact, even without its limitations. Third, the polysilicon in the refining process required to complete the 1,100-degree heat, the production process consumes large amounts of energy. Amorphous silicon Dell xps   m1330 battery  produced in a 200 degrees is a low power solar energy technology.

The photoelectric conversion efficiency of thin-film batteries have room for improvement, Oerlikon's laminated to connect Micromorph process makes the efficiency of solar cells for Fujifilm   np-95 increased by 50%, and improve the overall component power, solar photovoltaic manufacturers to provide a key competitive advantage.

3. Then the thin-film solar cells based on the many advantages and Oerlikon technology in thin-film efforts, can we determine, thin-film technology is the solar cell for Samsung   sb-lsm320 industry's future trend?

Crystalline silicon solar  vostro 1500 battery  are still in the solar market, accounting for a major share, but because of advantages of thin-film solar cells and their photothermal conversion rates gradually increase, and its development and become dominant in the market is inevitable, only a matter of time.

  At present, China is the world's largest solar cell ,Panasonic   cgr-d110 manufacturing base. But China's solar cell to a large extent dependent on exports. Now that China's solar panels but also sold to Germany and the U.S. long-distance markets, the large amount of Chinese-made batteries, also generated resentment in some countries. China has a huge potential consumer market of solar cells, sunny, labor resources, low prices, GDP grew faster than the state system, suitable for promotion of solar energy industry development, these are all Chinese nurture and develop the solar market advantages. However, the solar cell for Samsung   sb-l480   market in the early development of greatly influenced by government policies.

1/18/2010 - Introduction of Solar cell assembly processes

 
1. The battery test: because the randomness of the battery-chip manufacturing conditions, the Dell   precision m series battery  performance is different, we will make identical or similar battery assembled  together effectively, they should be classified according to their performance parameters; battery test  is that to classify them by  the size of testing the battery output parameters (current and voltage) .
 
2. Positive welding: It is to  solder  the convergence to the  Dell   312-0068 battery positive (negative) of the main gate line , convergence zone is  for the tinned copper belt. Welding heat source is the  an infrared lamp (using infrared thermal effect)
3. On the back of concatenation: back of the weld is to make 36 cells cascaded together to form a component of the string, currently we work  manually , the Dell   vostro 1500 battery  depends mainly on the positioning of a membrane with board, the operator use electric soldering iron and solder wire make "in front of cell "of the positive electrode (cathode) welded to the" behind the battery "on the back electrode (cathode).
4. Laminated lay: after  on the back of a good tandem and tested passing the component string, glass and cut a good EVA, glass fiber, backplane from Panasonic   cga-du21 battery are well prepared  for lamination according to a certain level. pre-coated layer of reagent (primer) for glass to increase the bonding strength of glass and EVA. When installed to ensure the battery strings and glass and other materials relative position, adjusting the distance between the Kodak   klic-8000 battery, and to laminate lay a solid foundation.
5. component lamination: a good battery will be laid into the laminating machine, through the vacuum component of the air out, and then heated to melt the EVA batteries, glass and back bonding together; the final when they are cooling ,take out components of Dell xps   m1330 battery .
6. Trimming: when laminated EVA melt ,because the pressure of reaching out, after curing ,it can become to the formation of flash, so the laminated should be removed.
7. Fitted box:it is  similar to  mounte  a frame for the glass ; mounte aluminum frame  for  the glass component to increase the intensity of the component, further sealing the  Dell xps   m1730 battery  components.
8. The welding junction box:welded  a box  in the back of the component lead for connections betmponents of the border and the electrode , test component of the pressure resistance and dielectric strength to ensure that components will not be damaged under the harsh ween the Canon   nb-2l battery and other equipment.
9. High-pressure test: high-pressure test is defined as  a certain voltage is applied between  the battery JVC bn-vf823 component frame and the electrode , test component of the pressure resistance and dielectric strength to ensure that componentswill not be damaged under harsh natural conditions (lightning, etc.) .
10. Battery component testing: the test objective is to calibrate the battery for Panasonic   cgr-s003 output power to test its output characteristics, and determine the quality grade components.

1/8/2010 - The reason of the battery explosion

In recent years, as people's living standards improve, the using battery,Sony   NP-FH100  frequency lis  ever-increasing , they often are inseparable from the battery ,such as digital cameras which people are familiar with , laptops and other electronic products . However, the frequency of accidents  is also rising ,which caused by the battery ,from the iPhone, Nokia's mobile phone to the cottage, the battery explosion are not uncommon(recently we have not heared such words about the Panasonic   CGR-S003battery explosion) even in our lives will be commonly used in cell No. 5 explosion.

Recently, the  exploding battery phenomena reported in network  ,I briefly summarized the reason of  battery explosion.

1. there are two reason of the battery explosion, one is a "non-normal use," such as the Kodak   KLIC-7004 battery is shorted, the battery used by the current is too large, non-rechargeable batteries Naqu charge, the temperature of using battery is  high , or it is negative anti-loaded when use the battery.
2. Another reason is that "there is no reason blew." Mainly it occurred in fake brand-name batterie,such as Sony   NP-FH100 battrey . Such an explosion is not because there are inflammable and explosive substances in the battery,but because of inferior material and impurities is within the battery, and also lacking substance, leading to the production of gas inside the battery,Canon   NB-4L, the internal pressure increase, so it is easy to "blew."
3. In addition, improper use of the charger can easily cause explosion  for rechargeable batteries,take  Kodak   KLIC-7001 battery for example. Article via:batterytalk   laptopinfo

12/27/2009 - a new fuel cell technology-Urine

U.S. scientists have recently used a new technology to male urine supplied power for cars, can also provide energy for home appliances and other equipment(it completely see as a kind of Sony NP-FC11battery to use).

Scientists extracted from the urine of large and cheap hydrogen by using nickel electrodes, while hydrogen can be as a motor fuel or used in the manufacture of fuel Samsung SLB-0637 battery ,It is reported that a cow's urine to provide adequate hot water energy for 19 families.

Urine, or hydrogen power technology is essentially the use of technology. Because the chemical composition of urine contains hydrogen(while hydrogen is the major components of battery,Canon BP-911),there is less electricity to obtain hydrogen through the urine than through water .rea molecules are the main component of urine, which contains four hydrogen atoms and two nitrogen atoms.put a special nickel electrodes from Samsung SLB-0637battery inserted into the urine container, and release hydrogen after pass on the current

The researchers invented a prototype fuel Sony NP-FH100 battery smaller urine, could only produce 500 milliwatts of electricity. Their next goal is to achieve industrial production and widespread use.It is estimated that for every gallon of urine is theoretically possible to ensure urine powered fuel Sony NP-FC11 vehicles running 90 miles ,a refrigerator-sized fuel Samsung SLB-0637can produce urine 1000 watts of power.

Chemists pointed out that a chicken farm produce electricity through the urine sufficient to maintain its normal operation(because it can be completely see as a Sony NP-FC11 battery-save up to prepare for using). It is reported that the livestock farms are required to excrete waste treatment in the United States ,the urine of new technologies for clean energy will undoubtedly be able to get double benefit effect.

12/22/2009 - changing plain paper into the battery by conductive coating

There is a the paper batterie,Digital Camera Battery with the composition of silver nanowires and carbon nanotubes ,it can be used for the portable device applications;The researchers also claimed that this newSamsung Battery , is a disposable type ,and it can also be produced into a variety of shapes according to the needs of different devices .

the battery is researched and developed  by Stanford University (StanfordUniversity) Assistant Professor of Materials Science and Engineering YiCui his team , it showed that it can be applied to the conductive coating,including the super capacitor (supercapacitors) to a low-cost Sony NP-FC11 electrodes and other parts ; His research team developed conductive paper, it based on a nanowire containing carbon nanotubes and silver nano-ink solution to a special coating;The kinds of paint will form one-dimensional structure of the film, and adhered in the fibrous paper surface.

Post-doctoral researcher at Stanford University use a special ink to coat ordinary paper, so that the ink is inside the nanotubes deposited on the paper surface, and cause a Sony Battery-coated paper after the paper will become a reservoir of high conductivity electrical components, The researchers will be followed by its plans to start charging LED;The kinds of batteries ,Samsung SLB-0637 can store a charge, better than capacitors, although its current per unit time (currentperunitoftime) are less capable.

The researchers said that the kinds of conductive paper also do super-capacitors for electric vehicles use because of its high surface volume ratio;Or it can be as a part of a large array of rechargeable batteries,Sony NP-BG1 and stored the excess electricity supply network at night,, and then released during the day when the power went out redistribution.

According to Stanford researchers tested, the kinds of paper can be repeated charge and discharge Samsung SBL-1974 battery up to 4 million times, the performance is 10 times than the traditional lithium-ion batteries.
