Batteries used in notebook computers are three main points: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Nickel Cadmium Ni-Cd, Ni-MH, lithium Li.

Is the first laptop to use Ni-Cd nickel-cadmium batteries, as battery technology was not advanced enough, so a lot of nickel-cadmium batteries with the shortcomings of headache, such as: bulky, heavy weight, small HP Envy 13 Battery capacity, short life, memory effects, etc. Therefore, the current nickel-cadmium batteries have basically been eliminated; the following detailed description is not it.

Then began to use nickel-metal hydride notebook (NlMH) battery that has a good cost performance and higher power, while “nickel-hydrogen battery is one of the most environmentally friendly battery, pay attention to environmental protection are strongly promoting the use of state nickel-metal hydride battery, as easy to recycle, and have the least damage to the environment. However, Ni-MH battery and lithium Xiang Bi, there are some drawbacks. Charge a long time and were heavier, capacity also smaller than lithium, the battery continued to discharge time is too short, there is memory effect, its memory even without the nickel-cadmium batteries so much, but still need to discharge; the user must be exhausted after the charge.

Ni-MH battery will replace lithium ion quickly (Li-ion) battery. Lithium will have a long time ago and began its use is not safe, there is often in charge when burning, burst, and this may be because the lithium element too active reason. Then there is the improved lithium-ion batteries, lithium inhibited by adding the element of active ingredients, so that lithium truly achieve a safe, efficient, convenient, and also followed the old lithium eliminated. Distinction between them is simple; the label from the battery can be Samsung IA-BP85ST Battery identified lithium as Li, lithium-ion battery Li-ion. Now, the notebook uses the so-called lithium, in fact, lithium-ion battery. Lithium-ion battery energy storage density, which can charge and discharge time is long sustained, generally about 3 hours. We can know the size of the battery capacity from the marked mAh (milliamp hours) to determine the value, such as the 3000mAh, 4000mAh and so on greater value, the greater the capacity of the battery.

Of course there are defects in lithium-ion batteries, such as charge and discharge times of high prices and less so. Lithium battery charging and discharging of the number of only 400-600 times, specially modified products, but many times 800. Charge a per day basis, the best lithium batteries, but also more than two years. The NiMH rechargeable battery can reach 700 times more than some quality products to charge and discharge up to 1,200 times, such a comparison, Ni-MH battery live longer than lithium batteries, and NiMH batteries than the lithium battery prices much lower. Hence, there is no perfect laptop battery.

Most common brands of laptop batteries are for the square. The market also has a small number of ultra-thin notebook using cylindrical batteries, such as SONY 505 series, Toshiba PROTEGE series. Battery weight dell Vostro 1220n battery varies according to materials and models, such as volume and shape of the same nickel metal hydride and lithium, but a difference of a lot of weight.

The size of the capacity marked mAh from the battery to determine its Chinese name is mAh. MA-hour size is directly related to the use of laptop time, but can not be generalized. Battery life notebook configurations with a great relationship, for example to speak, HP 6100 notebook with a PIII-M, MOBILITY RADEON graphics cards and many other energy saving technology hardware, with the 4000mAh battery, use the time up to 4 hours . Toshiba desktop CPU with 1800, although with a 4500mAh battery, use the time to 3 hours only. This also shows that the notebook is not only mAh battery related hardware, energy-saving technologies are very important.

The person said, “Within a few years, lithium-ion battery market will exceed the global mobile phone market size lithium-ion battery.

This change will lead to the battery manufacturing related to a new round of investment. At the same time, many new entrants to the lithium-ion battery manufacturers and materials related to the field of technology will enable more intense competition.

At the same time, the application of lithium-ion battery electric vehicle market shift from mobile phones and smart grid in the field.

Experts presented a series of data show that the global electric vehicle market to grow from 25 billion yen in 2009, surged to 300 billion yen in 2010, and in 2012 more than portable electronics market to reach 1.58 panasonic-dmw-bcf10-charger-p-71631.html”>DMW-BCF10 trillion yen. 2014 will reach 2.25 trillion yen - the market in 5 years will grow 90 times.

In addition, solar and wind power and other renewable energy power generation, large-capacity lithium-ion battery can store power to ensure stable power supply. For this application, only one product sodium sulfide battery.

Large-capacity lithium-ion battery applications are quite broad. After 2015, or even access to public buildings and homes. Grid Corporation of China is also active in 10MWh-class lithium-ion battery energy storage system pilot project.

Recently, Hefei Institute of Chemical and Materials Engineering, Dr. Tao Wei Bao research team to complete the “materials of solid oxide fuel cell and battery stack sealing technology research” project, successfully B170PW03 passed the provincial technically identified, the technology can provide new energy and auto zero contaminated “fuel cell.”

According to reports, the research project lasted five years, the key to solid oxide fuel cell materials and preparation of technical breakthroughs and achieve cell stack bonding between the various components and thermal expansion coefficient match. Provincial technically identified in the Commission’s experts agreed that this results in sealing and interconnect CLAA154WA01 materials, components and innovative design, materials and interconnect with excellent thermal Pipei performance of these materials by the construction of flat solid oxide fuel cells reactor can be run under thermal cycling conditions for power generation, in the preparation of the stack technology in the domestic advanced level.

It is understood that solid oxide fuel cell with fuel, wide adaptability and high efficiency energy conversion, solid state, modular assembly, zero pollution, etc, can use hydrogen, carbon monoxide, natural gas, liquefied petroleum gas, biomass gas and more gas, etc. kind of hydrocarbon fuel. Concentration of power in large, medium Distributor and small household cogeneration power plants and other civilian areas as fixed, as well as the ship power supply, transport vehicles and other mobile power supply HSD101PFW2 power supply, has wide application prospects.

January-June 2010, operating income 223 million Yuan, up 73.03 percent; a total profit of 048 million Yuan, up 65.65 percent; the owner of the net profit attributable to parent company 042 million Yuan, up 67.41 percent; basic per Shares gain 0.39 Yuan, of which the first two quarters of basic earnings per share of 0.28 Yuan.

Zhou Bang new capacity lithium ion battery electrolyte 5 years will increase 6 times. The company now has 1,200 tons of lithium-ion battery electrolytes annual production capacity by 2009, the company the potential of mining equipment, produced 1,500 tons of lithium-ion battery electrolytes, about 15% of the domestic market share. The company is in Nantong, Huizhou, and two new projects are expected to put into operation by 2015, all companies will have production capacity of 8600 tons lithium electrolyte, compared with 6.2 times the size now, will help consolidate the company’s domestic market, the top three position.

The new universe will keep domestic electrolytic capacitors state chemical industry today. The company has 16,000 tons of electrolytic capacitors in chemicals production capacity in the domestic market share above 30%, international market share of about 2.7%, is the leading enterprise in the industry. The company will have 49,600 tons by 2015, annual LT141X7 capacity, compared with the current growth of 260%. As the market leader, the new universe state in size, development, brand, quality and services, and leadership will ensure the steady development of the company piece of business.

Chemicals and solid polymer capacitor super capacitor electrolyte and promising in the future will increase rapidly. It is worth mentioning that the new universe of independent innovation state super capacitor electrolyte mastered the main solute - quaternary ammonium salt synthesis, in the international advanced level, become the only enterprise-scale production of quaternary ammonium salt.

As the company gradually put into operation the new project, the next three years in state revenues universe will be maintained in more than 30% growth. And high value-added products in the company’s overall revenue in the proportion of the improvement will be a small margin. As a result, the company’s gross profit margin can be maintained at a high level. 2010 to 2012 earnings per share were 0.90 Yuan, 1.17 Yuan and 1.41 Yuan. Taking into account the overall valuation of the GEM and the Shanghai and Shenzhen in the current lithium-ion battery chemicals listed companies positioned to recommend new state rating, target price of 54 Yuan.

We see from the data analysis: the stock rebounded from the LP089WS1 decline stopped since the trend of healthy cell concept relative to other listed companies in the overall increase is not significant; there is a strong compensatory growth requirement. Another quick win shows that the recent capital market is still small Masukura main, indicating shock pattern is expected to continue its own run, investors due attention.

General types of batteries can be divided into lead-acid batteries, maintenance-free lead-acid batteries and nickel cadmium batteries, taking into account the load conditions, use of the environment, life and costs, UPS usually selected VRLA maintenance free batteries. Its main feature is the positive charging plate produces oxygen through chemical reaction in the negative Banshang reduced to water, when used in the provision of water floating life of no application to maintain, so-called maintenance-free lead-acid batteries. Compared with the normal battery is maintenance-free, the process eliminates the use of added water ProBook 4710s/CT or distilled water, adjust the electrolyte surface of the work is not relieved of all maintenance work. On the contrary, for the realization of UPS uninterrupted power supply, we must be more careful to preserve and maintain a good lead-acid maintenance-free battery.

The main factors that affect the life and brief notes the following major factors affecting battery life and use of the process should pay attention to:

⑴ temperature greater impact on the battery. Ambient temperature is too high, battery charging will produce gas, the ambient temperature is too low, the battery will charge less, and it will affect battery life. Therefore, the general requirements for the ambient temperature around 25 ℃, UPS is also a floating voltage to set the temperature here. Practical applications, the battery generally 5 ℃ ~ 35 ℃ charge within, below or above 35 ℃ 5 ℃ will greatly reduce battery capacity and shorten battery life.

⑵ discharge depth of the impact on battery life is great. The deeper the depth of battery discharge, the fewer the number of its recycling, so should avoid the use of depth of discharge. Although the UPS has a battery low voltage protection, the general single-cell discharge to 10.5V or so, UPS will automatically shutdown. However, if the UPS is in light load discharge or discharge of the case load will cause the battery depth of discharge.

⑶ battery storage, transportation, installation, lost because of some self-discharge capacity. Therefore, after installation, put into use before the battery’s open circuit voltage should determine the remaining battery capacity, then a different approach to supplement charging of the battery. Spare batteries hold on, every 3 months should be a supplementary charge. By measuring the battery open circuit voltage to determine the battery is good or bad. To 12V battery, for example, if the open circuit HP Pavilion dv3 Battery voltage higher than 12.5V, the battery energy storage there for more than 80%, if the open circuit voltage lowers than 12.5V, the charge should be added immediately. If the open circuit voltage less than 12V, the battery stores electrical energy is less than 20%, the battery unusable.

⑷ battery charge and discharge currents generally expressed as C, C of the actual value of the battery capacity. For example, 100AH batteries, C = 100A. Panasonic maintenance free lead-acid battery is about the best 0.1C charge current, charge current can not exceed 0.3C. Charge current is too large or too small will affect battery life. General requirements for the discharge current between the 0.05C ~ 3C, UPS in normal use can meet this requirement, but also to prevent accidents from happening, such as battery short circuit.

⑸ charging voltage. As the UPS battery is alternate ways of working, electricity is in charge state under normal circumstances; only the power failure will discharge. To extend battery life, UPS charger general way with constant pressure limiting control to float state after the battery is full, each section about float voltage set to 13.6V. If the charging voltage is too high will cause the battery charging, the battery will charge less than the contrary. Charging voltage abnormality may be caused by the battery configuration error, or charger malfunctions. Therefore, when the battery is installed, be sure to pay attention to the battery specifications and the correctness of the number of different specifications, different batches of cells do not mix. Do not use inferior charger plus a charger, and installation to consider heat.

Currently, in order to further improve battery life, advanced UPS are using a ABM (Advanced Battery Management) three-stage intelligent battery management program that is charged into initialization charge, floating charge and the rest of three phases: the first is the constant flow equalization charge, charge the battery capacity to 90%; second stage is the floating charge, the battery charge to 100%, then stop charging; the third stage is a natural discharge, at this stage, the battery using its own leakage current discharge until the minimum voltage required, and then repeat the above three stages. Changed in this way before that is fully charged, the battery is still in the float state 24h a day, thereby extending battery life.

⑹ maintenance-free battery electrolyte absorption system as used in Hp Mini 311 normal use will not produce any gas, but if the user used improperly, resulting in battery charge, it will produce gas, then the internal pressure will increase the battery, the battery the pressure on the valve top opening, a serious cause battery burst.

⑺ UPS during operation, should pay attention to monitor the battery’s terminal voltage value, float current values, each battery voltage, battery and the DC bus to ground resistance and insulating state.

⑻ not individually increase or decrease the number of single cells in the battery load, which will cause imbalance and single battery charge heterogeneity, reducing battery life.

⑼ battery installed as far as possible in clean, cool, ventilated, dry place, and to avoid the sunlight, heaters or other heat source of radiation. Battery is being established should be placed, can not tilt. Connection between the terminals of each battery is in order to be stronger.

⑽ regular maintenance. Battery in use after a certain time should be regularly inspected, such as whether the observed abnormal appearance, measuring the battery voltage is average and so on. If long periods of power outage, the battery will always be in a state of charge, this would allow the activity of cell deterioration. So, even if power failure, UPS is also needed on a regular basis in order to keep the battery discharge test activity. Discharge test can generally be conducted for three months, the practice is sony NP-BK1 Battery contained with UPS - preferably more than 50%, and then disconnect the electricity, so UPS is in battery discharge status, discharge duration depending on battery capacity to run normally for a few ms tens of ms, after the restoration of electricity supply discharge, continue to charge the battery.

Understand and clearly affect the life of the main factors lead-acid batteries and in the use of the process should pay attention to our UPS system in the proper use and maintenance of lead-acid batteries is very helpful. Hope that in their daily work and safeguard the proper use of lead-acid batteries, it can be more rational use.

Lithium battery with physical light, efficient, low temperature (-40 ℃), etc, 0.3mm thick, stamp-size lithium batteries could be used for more than 5 years, in recent years is the phasing out of current use of sony-vgp-bps15-battery-p-73826.html”>VGP-BPS15 battery alkaline batteries and manganese batteries, widely used in many high-end home appliances and mobile phones.

Unlike the current use of lithium manganese batteries and alkaline dry batteries of the zinc chloride and potassium hydroxide aqueous electrolyte, which uses the organic solvent? Cathode using lithium manganese dioxide, lead fluoride, thinly chloride and other materials. Use of lithium metal foil anode with the general use of zinc chloride battery negative than the tendency of ionic strength, positive and negative voltage differential, so the work to improve the performance of lithium batteries.

However, lithium batteries are often in the course of fever, combustion phenomena, the light affect the host to use, re-host who will burn a fire. According to reports, Japan has taken place in recent years, more causes of lithium burning fever caused by the family fire.

So why lithium batteries, fever, burning it? Many of the original lithium battery materials in contact with water, chemical reactions can be dramatic and release a lot of heat leading to fever, burning phenomenon. Lithium manganese dioxide cathode, only a small drop of water can be stained with fever phenomenon. Lithium thinly chloride in contact with water, hydrochloric acid and sulfur dioxide in the formation, while the release of heat, several factors make a life lithium battery “fire”, so people must HP Pavilion dv3 Battery pay attention when using lithium batteries waterproof wet. Various host disabled, it should remove the lithium battery in a dry, low temperature and proper care to prevent and avoid improper use of lithium battery fires caused by household accidents.

First, to maintain proper temperature

Important factor affecting battery life is the ambient temperature, the general requirements of the battery manufacturer at the best temperature is between 20-25 ℃. Although the temperature of the battery discharge capacity has increased, the cost is greatly reduced battery life. According to experimental measurement, the ambient temperature exceeds the 25 ℃, for every increase of 10 ℃, the battery life would be cut by half. Used in the present UPS batteries is generally maintenance-free sealed lead-acid battery, universal design life is 5 years, the battery manufacturer requirements in an environment can be achieved. Not reach the environmental requirements, the length of its life there very different. In addition, the ambient temperature increase will lead to increased chemical activity inside cells, which produce large amounts of heat; in turn boosts the temperature of the surrounding environment, this vicious cycle will accelerate shorten battery life.

Second, regular charge and discharge

UPS power supply in the float voltage and discharge voltage, at the factory have been debugging the rating, the size of the discharge current increases as the load increases, the use of the load should be a dell-inspiron-15z-battery-p-98573.html”>Inspiron 15z reasonable adjustment, such as control computers and other electronic equipment the use of number of machines. In general, UPS load should not exceed 60% of rated load. In this context, the battery discharge current will not over-discharge.

UPS for long-term with power connected, the supply of high quality, rare power cut in the use of the environment, the battery charge for long at a floating state, so time will cause the battery to chemical energy and electrical energy conversion activity decreased with each other to speed up aging and shorten life. Therefore, generally every 2-3 months to be fully discharged once the battery discharge time can determine the capacity and load size. After a full load discharge, it required more than 8 hours to recharge.

Third, use of communication

Currently, most large and medium-sized UPS are equipped with computer communication and process control, etc. can be operational performance. The corresponding software installed on PC, through serial / parallel port connection UPS, run the program; you can use the computer to communicate with the UPS. General with information search, parameter settings, set the timer, automatic shutdown and alarm functions. Through the information search, you can get mains input voltage, UPS output voltage, load utilization, battery capacity utilization, machine temperature and electric frequency and other information; through parameter setting, you can set BN-VF823 the basic characteristics of UPS, battery duration and batteries run out of alarms. With these intelligent operation, greatly facilitates the use of UPS power supply and battery management.

Fourth, timely replacement of waste / bad battery

Medium and large UPS power supply with the current number of batteries, from 3 to 80 ranges, or even more. The single circuit to connect the battery through the battery, DC power supply to meet the needs of UPS. UPS operation in continuous use, performance and quality due to differences in individual cell performance degradation, storage capacitance is below standard and damage is unavoidable. When the battery pack in a / some cells is damaged, the maintenance staff should inspect each battery test, remove the damaged battery. Replacement of the battery, it should seek to purchase the same type of battery manufacturers, prohibition of anti-acid batteries and sealed batteries, the batteries of different specifications.

The company said it plans to add 620MW at the end of 2010 production capacity to 800MW, the initial phase of 400 MW plant will be completed in the first half of 2011.

Kun Xilin, chairman of the new daylight, said he expects the battery will maintain the current price stability, the company’s 25% -30% of the raw material prices determined by the previous contractual agreement, NeoSolar spot market to purchase U.S. silicon Yue $ 50 - $ 55/kg.

Neo Solar Power2010 peer solar cells after the first half sony-np-fc11-charger-p-65937.html”>NP-FC11 of the company Gintech Energy Corporation, its first half revenues of NT 7.49 billion Yuan, up 96.1% year on year, 1.31 billion after-tax profits of NT.

The report submitted by Mark Allen said the new energy future will be woven into clothing or other fabric in bulletproof vests, to any size and shape of the electronic devices to provide power. He is a Massachusetts Institute of Technology (MIT) Cheke Research Group, a postdoctoral researcher. These batteries can be smart phones, GPS devices and other portable electronic devices powered. Allen said: “We are discussing the fabric is also a battery. This battery has been woven into the fabric panasonic-vw-vbg260-battery-p-73258.html”>VW-VBG260 in the future, much high-tech equipment for electricity, including hand-held radios, GPS devices and personal digital assistants. In addition, they also are applied for the everyday use of mobile phones and smart phone charging. ”

Battery using bipolar (positive and negative, separated from the electrolytes) take chemical energy into electricity, producing currents. Allen 240th American Chemical Society annual meeting, said development of new iron with fluoride negative, will soon be able to produce and light, flexible and nice batteries, rechargeable batteries, compared with the current, this cell loss minimum , efficiency (also known as the rate of charge) higher. Allen extended the last year, scientists from the Massachusetts Institute of Technology and his colleagues thoroughly breakthrough work, they are the first batch of the virus as a lithium-ion battery positive and negative biological template of the people. This is called the virus bacteriophage M13, the outer layer made up of protein, is the gene within the nucleus. It is infected with bacteria to humans.

Allen said: “the M13 phage as a template is a live example of green chemistry is the production of a battery of new methods of environmental protection. Processing of all materials is at room temperature and water carried.” He said that these material harm than the current materials used in lithium ion batteries smaller, since they produce less heat, which reduces the flammability risk. Belcher biological materials was also only in the testing and improving the virus early stages of cell materials, including for nikon EN-EL4a Charger the provision of electricity for the monitoring of the UAV. Allen said the development of lightweight, durable battery, used to make rechargeable clothing, military personnel and civilians alike.

He said: “Most soldiers have to carry a few pounds of batteries. But if you can pack into their clothes, you can reduce a lot of weight for them. Businessmen who frequently travel is also true, to a computer, charge cell phones and other electronic devices, they often need to carry large amounts of batteries and chargers independence. With this new type of battery, they can more easily travel. ”

River lithium-ion battery with cheap price, no pollution, high safety, Acer UM09A41 Battery high power, etc, this battery could be used for future wind power, solar power and other energy storage, smart grid peak and valley load regulation and short-distance electric buses and so on, but subject to constraints and poor circulation has been unable to put into practical application.

1994 “Science” (”Science”) on the first reported use of aqueous electrolyte, a lithium-ion batteries, the practical application of this energy density than lead-acid batteries, but the cycling performance is poor, so that the battery short-lived. To improve the cycle performance, increased battery times in the past mainly focused on research appropriate choice of electrode materials to improve the cycle performance, but try to be ineffective in key issues, usually after 100 cycles is charged 100 times, maintain the rate of battery capacity below 50%.

Professor Xia Yongyao discussion group has been engaged since 2004, lithium-ion intercalation compound in aqueous solution of electrolyte, the researchers found that lithium intercalation compound in aqueous electrolyte electrode reaction than the complex in the organic electrolyte, in addition to consider the electrode material itself, the fujitsu FPCBP222 process of lithium ions in the stability, the analysis must consider the hydrogen of water, water analysis of the reaction of oxygen, proton competition embedded in aqueous solution, the electrode material in aqueous solution and so on.

After a series of experiments and analysis, the researchers confirmed the presence of water and oxygen, as the battery negative electrode material may be caused by water oxygen oxidation is a lithium ion battery main reason for capacity fading, while the elimination of oxygen through the oxidation of sealed batteries, select suitable negative electrode materials and carbon coated cathode can greatly enhance the battery cycle performance, 10-minute battery charge and discharge Compaq Mini 311c Battery rate of 100 times from less than 50% of the capacity to maintain up to 1000 can charge and discharge cycles, capacity retention rate more than 90%.

Professor Xia Yongyao told reporters: “Although research to improve the solution cycle performance of lithium ion batteries provide an important guide, but the water lithium-ion batteries will really have a certain distance from practical application.”
