The lithium iron phosphate battery ( LiFePO. 4 battery) or LFP battery ( lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate ( LiFePO. 4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and
Its charge–discharge curves show a characteristic flat curve at ∼3.4 V versus Li + /Li, and with the limited theoretical capacity of ∼170 mA h g −1. The conductivities of LiFePO 4 is low (∼10 −9 S cm −1) and it is difficult to be practical at the pristine state. However, its electrochemical performances can be largely improved by

Lithium iron phosphate (LiFePO4) is also available in the 18650 format offering high cycle life and superior loading performance, but low specific energy (capacity). A battery may discharge at a steady load
Stage 1 charging is typically done at 10%-30% (0.1C to 0.3C) current of the capacity rating of the battery or less. Stage 2, constant voltage, begins when the voltage reaches the voltage limit (14.7V for fast charging SLA batteries, 14.4V for most others). During this stage, the current draw gradually decreases as the topping charge of the

The bulk charging voltage is the initial and highest voltage applied during the charging process. For LiFePO4 batteries, the typical bulk charging voltage is around 3.6 to 3.8 volts per cell.

While voltage-based SoC works reasonably well for a lead acid battery that has rested, the flat discharge curve of nickel- and lithium-based batteries renders the voltage method impracticable. The discharge voltage curves of Li-manganese, Li-phosphate and NMC are very flat, and 80 percent of the stored energy remains in the
LiFePO4 batteries exhibit a very flat voltage curve during discharge. This means the voltage remains relatively constant for most of the discharge cycle, providing a stable power output.
