充放电性能 (Electrical Characteristics)
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 | ≥1500mAh |
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% |
