Lithium iron phosphate batteries are used to make lithium-ion secondary laptop battery batteries, and now the main direction of motive power batteries, the relative NI-MH, Ni-Cd batteries have a great advantage.

Lithium iron phosphate power battery seven advantages:

1, long life, long-life lead-acid battery cycle life of about 300 times the maximum also 500 times, while the lithium iron phosphate power battery, cycle life of more than 2,000 times, the standard charge (5 hours rate) use, it can 2,000 times. With the quality of lead-acid battery is the "new for half a year old for six months, another half a year to maintain the maintenance," at most 1-1.5 years, while the lithium iron phosphate batteries used under the same conditions, it will reach 7-8 years. Taken together, cost performance will be four times more than lead-acid 08K8198 batteries.

Second, the use of safe, lithium iron phosphate completely solve the cobalt and manganese lithium lithium security risk issues, cobalt and manganese lithium lithium in the strong collision will produce an explosion under the right pose a threat to the safety of consumers, while the phosphorus acid, lithium iron to undergo rigorous safety testing, even in the worst traffic accident will not produce an explosion.

3, can be high current 2C fast charge and discharge, under the dedicated charger, 1.5C within 40 minutes you can recharge the battery is full, the starting current of up to 2C, but now there is no such performance of lead-acid batteries.

Fourth, high temperature, lithium iron phosphate peak heating up to 350 ℃ -500 ℃ and the lithium manganese oxide and lithium cobalt only about 200 ℃. Wide operating temperature range (-20C - +75 C), a high-temperature characteristics of lithium iron phosphate peak heating up to 350 ℃ -500 ℃ and the lithium manganese oxide and 08K8197 lithium cobalt only about 200 ℃.

5, high-capacity.

6, no memory effect. Rechargeable batteries are always in full and hold finished work under conditions, capacity will quickly lower the value of rated capacity, a phenomenon called the memory effect. Such as nickel-metal hydride and nickel cadmium batteries existence of memory, but no such phenomenon of lithium iron phosphate batteries, the battery no matter at what state of charge can be as with the use, without first release finished recharge.

7, green environmental protection. The battery does not contain any heavy metals and rare metals (nickel-metal hydride batteries be rare), non-toxic (SGS certification), non-polluting, in line with European RoHS regulations, for the absolute battery green card. Lead-acid 92P1075 batteries but there are high levels of lead in their waste after it is handled properly, will still be enough into the secondary pollution to the environment, while the lithium iron phosphate material in terms of production and use, are non-polluting, so the battery has included in the "Tenth Five-Year" period of "863" National High-tech development plan, a national focus to support and encourage the development of projects. With China's accession to WTO, China's electric bicycle exports will increase rapidly, and now into Europe and the United States has asked the electric bicycle is equipped with pollution-free battery.

Lithium iron phosphate batteries have their drawbacks: for example, lithium iron phosphate cathode material of the tap density smaller, and so the capacity of lithium iron phosphate battery is greater than the size of lithium cobalt oxide such as lithium-ion batteries, so do not micro-batteries advantage.

Lithium iron phosphate battery Prospects

Lithium as a lithium iron phosphate power battery material is only in recent years appeared to do, the domestic development of a large-capacity ThinkPad R40 lithium iron phosphate battery is in July 2005. Its safety performance and cycle life are unmatched by other materials, which is what power batteries of the most important technical indicators. 1C charge-discharge cycle life up to 2000 times.
