充放电性能 (Electrical Characteristics)
NO 项目(ITEM) 测试方法(Testing Instruction) 要求(Requirements)
1 Standard Charge
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 Rated Capacity
初始容量 Measure discharge capacity with discharge current 0.2C to 3.0V cut-off within 1 hour after standard charge.
标准充电方式充电后，以0.2C电流放电至3V的容量 ≥2000mAh
3 Cycle Life
循环寿命 Measure the capacity after 500 cycles of standard charge and discharge at 0.5C current to 3.0 V cut-off
标准充电方式充电后，0.2C放电至3.0V，如此循环500次后电池的剩余容量 ≥ 80% of Rated Capacity
初始容量的80%
4 Storage Characteristics 储存性能 Capacity after 30days storage at 25℃ from standard charge
标准充电方式充电后，25℃下储存30天后的容量 Retention capacity
≥90%
剩余容量≥90%
Capacity after 7days storage at 60℃ from standard charge
标准充电方式充电后，60℃下储存7天后的容量 Recovery capacity
≥ 90%
剩余容量≥90%
