Lithium-ion battery has the following advantages:

1. High voltage, voltage of single battery go up to 3.6-3.9V,and it is 3 times than a Ni-Cd, Ni-H batteries ,such as
   Dell xps m1530 battery.
2. Larger specific energy , at present real energy is 100-125Wh/kg and 240-300Wh / L (2 times higher than Ni-Cd, 1.5 times higher than Ni-MH), the future, as technological development, specific energy up to 150Wh/kg and 400 Wh / L
3. Long cycle life, in general, Lithium-ion battery can reach more than 500 times, or even 1000 times or more. For a small electrical current discharge, the battery will double the lifespan of electrical appliances competitiveness.
4. Safety performance is good, and pollution-free, no memory effect. like the Dell latitude d820 battery . As the predecessor of Li-ion batteries, the
   formation of lithium dendrite easy to short-circuit reduce its application areas: Li-ion does not contain cadmium, lead, mercury and other elements of the environment pollution: Some processes (such as sintered) and Ni-Cd batteries there is a major drawback for the "memory effect", seriously hindered the use of batteries, but Li-ion does not exist at this problem.
5. Self-discharge is small, after full of electricity at room temperature Lithium-ion battery is storaged for a month ,the self-discharging rate is about 10%, much lower than Ni-Cd of 25-30%, Ni, MH 30-35%.
6. Can quickly charge and discharge,for one thing ,the ,Olympus li-12b . 1C charging capacity can reach more than 80% of the nominal capacity.

   
   

7. Operating temperature range is high, operating temperature is -25 ~ 45 ° C, with the electrolyte and the positive improvements, it is hoped to broaden the -40 ~ 70 ° C.

Lithium-ion batteries also exist some disadvantages, such as:

1. Battery costs are higher,take theNikon en-el4 battery for example. it mainly reflected in the price of LiCoO2 cathode materials for high-(Co resources to small), electrolyte purification system difficult.
2. Not high-current discharge. As the organic electrolyte system, and other reasons, the battery internal resistance is big ,compared to other type of batteries for Fujifilm np-40 . Therefore, I demand a smaller discharge current density, the discharge current at 0.5C below normal, only suitable for small and medium-current electrical use.
3. Iit need to protect line control.

• Overcharge protection: Battery over charging would undermine the positive structure, for one thing ,the Dell inspiron 1300 akku . which affects the performance and life; the same time, the overcharge to the electrolyte decomposition, excessive internal pressure caused by leakage and other problems; and therefore must be under constant pressure 4.1V-4.2V charge;
• Over-discharge protection: over-discharge recovery of active substances will cause difficulties, they also need protection circuit control.

 

Some people might be familiar to lithium batteries from mobile phones,such as Dell inspiron 6400 battery. In fact, it is being used in many household appliances. Needless to say, lithium battery is efficient, lightweight, and so its benefits are opened and promoted to use rapidly. But, you know, use carelessly, it will make you provoke "fire" upper to your body?

Lithium batteries have a body of light, high efficiency,like the Dell inspiron e1505 battery low temperature (-40 ℃) etc., 0.3mm thick, stamp-sized lithium battery can be used continuously for more than five years, in recent years are being phased out are used in alkaline batteries and manganese batteries, widely used in many high-end home appliances and mobile handsets.

Unlike alkaline manganese dry battery of the zinc chloride and potassium hydroxide aqueous electrolyte, Lithium batterie uses an organic solvent. Lithium Battery Cathode use manganese dioxide, lead fluoride, thionyl chloride and other materials. Anode used lithium metal foil anode ,compared with the general use of zinc chloride batteries, take the Dell latitude d600 battery for example ,ionization tendency is strong, and positive and negative voltage difference is big, so that improving the effectiveness of lithium batteries.

However, there are fever and burning phenomenon in the using course of lithium batteries often , it have the light impact to the host, in serious cases ,it will also cause a fire burned down the host. It is reported that Japan has in recent years there were several causes of Li-ion battery heat caused by the family fires burning.

So why lithium batteries can cause fever and burning? after many of the original lithium battery materials contact with water,for one thing ,the Jvc bn-v428 battery ,severe chemical reaction can occur, and release a lot of heat leading to fever, burning phenomenon. Manganese dioxide lithium battery cathode only contact with a small drip ,it can dip fever phenomenon. Lithium thionyl chloride batteries contact with water in the generation of hydrochloric acid and sulfur dioxide, while the release of heat, several factors make life lithium batteries to become the "fire" ,and therefore people must pay attention to water-proof, anti - wet when using lithium batteries . A variety of host are disabled, they should remove the batteries, and placed them in dry, low temperature at the proper custody, to prevent and avoid battery fires and household accidents ,due to inappropriate use of lithium battery for Samsung sb-l110 .

How to Choose Battery

1. Choose the "National Inspection-free", " famous brand" (such as Dell inspiron 1520 battery )logo and the local brand-name batteries battery products, the quality of these products have a certain protection.
2. According to the requirements of electrical appliances, select the appropriate cell types and specifications of size and power apparatus ,and according to the size and characteristics of power, purchase equipment for electricity battery.

4. Pay attention to checking the appearance of the battery,should buy packaged refined appearance neat, clean, no signs of battery leakage.
5. Pay attention to the battery symbol, the battery for Canon bp-522 should be marked with the production mark the make, battery polarity, the battery model, nominal voltage, trademarks, etc.; sales package (such as two heat-shrinkable, or four heat-shrinkable, or hang tag card ) It should have the Chinese factory, manufacturing date and shelf-life or shelf life of the deadline marked the implementation of the standard number. Purchase of alkaline zinc-manganese battery ALKALINE, or whether one should look at models LR words.
6. Due to mercury batteries harmful to the environment, in order to protect the environment, the purchaser should select the label marked "mercury-free", "0% mercury," and "no added mercury" indication of battery,take the Jvc bn-v408 for example .

Should pay attention to the use of batteries :

1. Electrical appliances and battery contacts should be clean, if necessary, wipe with a damp cloth until the dry loaded correctly marked by polarity. When loading the battery to see for the polarity ( "+" and "- ") to install an extremely important ,and should be the specification requires the installation of electrical appliances with the use of the recommended batteries; do not follow instructions required will lead to equipment failure, damage to electrical appliances and / or battery.
2. Should also replace all batteries in a battery, do not mix old and new batteries together; the same model but a different type or brand of battery electrochemistry do not mix, such as Canon bp-711 andCanon bp-911 , and otherwise it would be a set of batteries in use in some of the battery over-discharge state, thereby increasing the possibility of leakage.
3. Can not heat for a one-time or charge the battery for recycling, or they may explode.
4. Can not make the battery short-circuit to avoid battery leakage and resulting damage to the heat generated by insulated packaging.
5. Electrical appliances should be removed from the battery for a long time without using , the power should be closed after using to avoid the battery going on to discharge its internal chemical reaction took place which led to leakage of the negative.
6. Used batteries for 12" apple powerbook g4 akku should not arbitrarily discarded, as far as possible separated from other garbage running.

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

battery

• 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 lithium-ion Dell inspiron 8600m 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.

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 710m 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 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.
