测试方法(Testing Instruction) |
要求(Requirements) |
1 |
Standard Charge 标准充电 |
Charging the cell initially with c***tant current at 0.2C and then with c***tant 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 |
此方式为仲裁充电方法 |
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 |
≥2500mAh |
3 |
Cycle Life 循环寿命 |
Measure the capacity after 300 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300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% |
