Test Method and Condition |
Criteria |
1 |
Standard Charging 标准充电 |
Charging the cell initially with constant current at 0.5C and then with constant voltage at 4.2V till charge current declines to 0.05C 先用0.5C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 discharging capacity of the cell, which is measured with discharging current of 0.2C with 3.0V cut-off voltage after standard charging. 该容量是指标准充电后,0.2C放电至3.0V截止电压所放出的容量。 |
≥ 2800mAh |
3 |
Discharging at High- Temperature 高温放电
|
1) Standard Charging标准充电 2) Put the cell into 80±2℃ high temp oven for 2 hours and discharge at 0.2C CC to 3.0V at the high temperature. 在80±2℃的高温箱中恒温2h,在该温度下0.2C恒流放电至3.0V。 |
Discharging capacity初始容量85%
|
4 |
Discharging at Low Temperature 低温放电 |
1) Standard Charging标准充电 2) Put the cell into -40±2℃ high temp oven for 4 hours and discharging at 1C CC to 2.5V at the high temperature. 在-20±2℃的高温箱中恒温4h,在该温度下1C恒流放电至2.5V。 |
Discharging capacity初始容量60%
