The battery was discharged at a constant current of 0.5C to a cut-off voltage of 2.00V at 25°C. After stabilizing for 30 min, the cells were charged to a cut-off voltage of 3.80 V at various C rates at 25 °C.
The lifepo4 battery is charged at a constant current of 0.5C to an upper charge voltage of 3.80V at 25°C. After stabilizing for 30 min, discharge to a cut-off voltage of 2.00 V at different C-rates.
The lifepo4 battery was charged at 25°C with a constant voltage of 0.50 to an upper charge voltage of 3.80V. They were then stored at a range of temperatures for 8 h before discharge. The discharge test of the cell should be carried out with a constant current of 0.5C to a cut-off voltage of 2.00V.
