RT Cycle

After 30,000 cycles, the residual capacity/ original discharge capacity≥80%.( The cell is tested at 20±3℃, 65±20% relative humidity and 86kPa~106kpa. First fully charge the cell with standard charging method, then discharge the cell with standard discharging method, the time interval between charging and discharging should not less than 30mins, then repeat the steps mentioned above.)
