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%
