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). 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.
| Chemistry | Voltage | Energy Density | Working Temp. | Cycle Life | Safety | Environmental | Cost based on cycle life x wh of SLA |
| LiFePO4 | 3.2V | >120 wh/kg | -20-60 °C | >2000(0.2C rate, IEC Standard) | Safe | Good | 0.15-0.25 lower than SLA |
| Lead acid | 2.0V | > 35wh/kg | -20 - 40°C | >200 | Safe | Not good | 1 |
| NiCd | 1.2V | > 40wh/kg | -20 - 50 °C | >1000 | Safe | Bad | 0.7 |
| NiMH | 1.2V | >80 wh/kg | -20 - 50 °C | >500 | Safe | Good | 1.2-1.4 |
| LiMnxNiyCozO2 | 3.7V | >160 wh/kg | -20 - 40 °C | >500 | better than LiCo | OK | 1.5-2.0 |
| LiCoO2 | 3.7V | >200 wh/kg | -20 - 60 °C | > 500 | Unsafe w/o PCM | OK | 1.5-2.0 |
Major parameters of protection board:
