LiFePo4 cell (Abbreviated as LFP or LF) is a lithium-ion battery using lithium iron phosphate as the cathode material and carbon as the negative electrode material, with a single cell rated at 3.2V and a charging cut-off voltage of 3.6V~3.65V. Lifepo4 cell has the advantages of high operating voltage, high energy density, long cycle life, good safety performance, small self-discharge rate and no memory effect.
| Electrochemistry: LiFePo4 cell is also composed of three parts: positive electrode, negative electrode, and electrolyte. Positive: Li-ions are embedded during discharge and detached during charging. • Charging: LiFePO4 → Li1-xFePO4 + xLi+ + xe− • Discharge: Li1-xFePO4 + xLi+ + xe− → LiFePO4 Negative: Li-ion detachment during discharge and insertion during charging. • Charging: xLi+ + xe− + 6C → LixC6 • Discharge: LixC6 → xLi+ + xe− + 6C |  |
