Lithium Iron Phosphate (LiFePO4, LFP) is kind of Li-Ion rechargeable battery for high power applications, such as EV , Energy storage, Power Tool and so on. LFP cells feature with high discharging current, non explosive, long cycle life (>2000@0.2C rate, IEC Standard), but its energy density is lower than normal Li-Ion cell (Li-Co) (higher NiMH cell). Please click Knowledge on LiFePO4 battery to learn more detail. LFP cell has 3.2V nominal working voltage and shall be cut-off power at 3.6-3.8V per cell during charging. Please see the table below to see comparison between LFP and other rechargeable batteries. LFP battery has the lowest cost if considering its long cycle life.
