Lithium Iron Phosphate Batteries

Lithium Iron Phosphate Batteries are a type of lithium-ion battery with a cell voltage of 3.2 V or 3.3 V. Lithium Iron Phosphate (LiFePO4) is used as cathode material in place of conventional lithium cobalt oxide (LiCoO2). The anode is made of graphite or hard carbon with intercalated lithium. LiFePO4 was first used in 1997 as cathode material for lithium ion batteries. It replaces the commonly used lithium cobalt cathode. The main reasons to use it as a replacement are improved environmental performance and higher reliability. The main applications of this technology include military, electric mobility, storage, and mobile devices with a focus on safety, such as in medical technology.
