Battery performance

LiFePO4 battery is a kind of lithium-ion battery which uses LiFePO4 as cathode material.

1)Security

In the molecular structure of LiFePO4, the chemical bond P-0 is stable and not easy to decompose. At high temperature or overcharge, the structure is stable and reliable, so it has good safety

2)Long life

LiFePO4 power lithium battery has a single cycle life of more than 3000 times and supports fast charging. Lead acid batteries of the same quality are "new half a year, old half a year and maintenance half a year", with a maximum of 1-1.5 years. When LiFePO4 battery is used under the same conditions, its theoretical life will reach 7-8 years. Considering comprehensively, the ratio of performance to price is more than 4 times of that of lead-acid battery theoretically. High current discharge can charge and discharge quickly at high current 2C. Under the special charger, it can be charged within 40 minutes at 1.5C.

3)High temperature performance

The electrothermal peak value of LiFePO4 can reach 350 ℃ - 500 ℃, while that of LiMn2O4 and LiMn2O4 is only about 200 ℃. The working temperature range is wide (- 20 ℃ - 75 ℃), and it has high temperature resistance. The peak value of lithium iron phosphate can reach 350 ℃ - 500 ℃, while LiMn2O4 and LiMn2O4 are only about 200 ℃.

4)high-capacity

When the battery is always working under the condition of full capacity, the capacity will be lower than the rated capacity quickly. This phenomenon is called memory effect. Lithium batteries have no memory effect and have larger capacity than ordinary batteries (such as lead-acid). Capacity 5ah-1000ah (monomer)

5)Light weight

The volume of LiFePO4 battery with the same capacity is 2 / 3 of that of lead-acid battery, and its weight is 1 / 3 of that of lead-acid battery.

6)environment protection

Lithium iron phosphate batteries are generally considered to be free of any heavy metals and rare metals (Ni MH batteries need rare metals), non-toxic (SGS certification), pollution-free,

It meets the requirements of European and American ROHS certification, and is recognized as a green environmental protection battery.
