Discharge capacity at 1C(Min)

After standard charge, the capacity shall be measured on 1C discharge till the voltage discharge to 2.0V

Cycle life

Charging and discharging cell as blew conditions
0.2CC-CV to 3.65V, 0.01C cut off
0.2CD to 2.0V
Continuous charge and discharge for 2000 cycles, the capacity will be measured after the 2000^th cycle.

Storage performance at room temperature

The cell is to be charge in accordance with standard charge condition at 20~25℃,then storage the cell at an ambient temperature 20~25℃ for 28 days. Measure the capacity after 28 days with 0.2C at 20~25℃ as retention capacity. Then charge and discharge with 0.2C at 20~25℃ as recover capacity.

Recover capacity

Storage performance at high temperature

The cell is to be charge in accordance with standard charge condition at 20~25℃,then storage the cell at an ambient temperature 60±2℃ for 7 days. Measure the capacity after 7 days with 0.2C at 20~25℃ as retention capacity. Then charge and discharge with 0.2C at 20~25℃ as recover capacity.
