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%
