充放电性能
NO. | Items | Test Method and Condition | Criteria |
1 | Standard Charging 标准充电 | Charging the cell initially with constant current at 0.2C and then with constant voltage at 4.2V till charge current declines to 0.05C 先用0.2C恒流充电至4.2V,再恒压4.2V充电直至充电电流≤0.05C |
|
2 | Initial Capacity 初始容量 | The capacity means the discharge capacity of the cell, which is measured with discharge current of 0.2C with 2.5V cut-off voltage after standard charge. 该容量是指标准充电后,0.2C放电至2.5V截止电压所放出的容量。 | ≥ 2.2Ah |
3 | Discharging at High Temperature 高温放电
| 1) Standard Charge标准充电 2) Put the cell into 60±2℃ high temp oven for 2 hours and discharge at 0.2C CC to 2.5V at the high temperature. 在60±2℃的高温箱中恒温2h,在该温度下0.2C恒流放电至2.5V。 | Discharging capacity初始容量90%
|
4 | Discharging at Low Temperature 低温放电 | 1) Standard Charge标准充电 2) Put the cell into -40±2℃ high temp oven for 4 hours and discharge at2.5A for 5 min and then change to1A to 2.5V at this temperature. 在-40±2℃的高温箱中恒温4h,在该温度下恒流440mA放电35分钟,然后改用220mA恒流放电至2.5V。 | Discharging capacity 初始容量85% |
