Lithium Iron Phosphate Battery
The lithium iron phosphate (LiFePO4) battery, also called LFP battery, is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO4 as a cathode material. LFP chemistry offers a longer cycle life than other lithium-ion approaches. LiFePO4 has higher current or peak-power ratings than LiCoO2.
LiFePO4 cells experience a slower rate of capacity loss (aka greater calendar-life) than lithium-ion battery chemistries such as LiCoO2 cobalt or LiMn2O4 manganese spinel lithium-ion polymer batteries. After one year on the shelf, a LiFePO4 cell typically has approximately the same energy density. Because of its low cost, non-toxicity, the high abundance of iron, its excellent thermal stability, safety characteristics, electrochemical performance, and specific capacity (170 mA•h/g, or 610 C/g), it gained more and more market acceptance.
