Lifepo4 Battery
Nov 01, 2018

The lithium iron phosphate (LiFePO
4
) battery
, also called LFP battery (with "LFP" standing for "lithium ferrophosphate"), is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO
4
 as a cathodematerial, and a graphitic carbon electrode with a metallic current collector grid as the anode. The specific capacity of LiFePO
4
 is higher than that of the related lithium cobalt oxide (LiCoO
2
) chemistry, but its energy density is slightly lower due to its low operating voltage. The main problem of LiFePO
4
 is its low electrical conductivity. Therefore, all the LiFePO
4
 cathodes under consideration are actually LiFePO
4
/C.[3] Because of low cost, low toxicity, well-defined performance, long-term stability, etc. LiFePO
4
 is finding a number of roles in vehicle use, utility scale stationary applications, and backup power.
