Reversible extraction of lithium from LiFePOĤ was demonstrated. LiFePOĤ was then identified as a cathode material belonging to the polyanion class for use in batteries in 1996 by Padhi et al. Goodenough first identified the polyanion class of cathode materials for lithium ion batteries. Notably, the energy density of Panasonic’s “2170” NCA batteries used in 2020 in Tesla’s Model 3 is around 260 Wh/kg, which is 70% of its 'pure chemicals' value.Ĥ is a natural mineral of the olivine family ( triphylite). The energy density of an LFP battery is lower than that of other common lithium ion battery types such as nickel manganese cobalt (NMC) and nickel cobalt aluminum (NCA), and also has a lower operating voltage CATL's LFP batteries are currently at 125 watt hours (Wh) per kg, up to possibly 160 Wh/kg with improved packing technology, while BYD's LFP batteries are at 150 Wh/kg, compared to over 300 Wh/kg for the highest NMC batteries. With patents having started to expire in 2022 and the increased demand for cheaper EV batteries, LFP type production is expected to rise further to surpass lithium nickel manganese cobalt oxides (NMC) type batteries in 2028. Chinese manufacturers currently hold a near monopoly of LFP battery type production. As of September 2022, LFP type battery market share for EV's reached 31%, and of that, 68% was from Tesla and Chinese EV maker BYD production alone.

The lithium iron phosphate battery ( LiFePOĤ battery) or LFP battery ( lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate ( LiFePOĤ) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode.īecause of their lower cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power.
