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 ≤ 0.02C.
先用 0.2C 恒流充电至 4.2V ,再恒压 4.2V 充
电直至充电电流≤ 0.02C。
N.A.

Initial
Capacity
初始容量
The capacity means the discharge capacity of the
cell, which is measured with discharge current of
0.2C with3.00V cut-off voltage after the standard
charge.
该容量是指标准充电后,0.2C 放电至 3.00V 截
止电压所放出的容量。
2≧ 500mAh

Cycle Life
循环寿命
Test condition:
Charge: 0.5C to 4.2V
Discharge: 0.5C to 3.00V
80% or more of 1
st
cycle capacity at 0.5C
discharge of Operation
测试条件:
充电:0.5C 充电到 4.2V
放电:0.5C 放电到 3.00V
当放电容量降至初始容量的 80%时,所完成的
循环次数定义为该电芯的循环寿命
300cycles:
≥ 80%

Self-discharge
自放电
After the standard charging, storied the cells under
the condition as No.4.3.4 for 30days, then
measured the capacity with 0.2C till 3.00V
标准充电后, 在 No.4.3.4 条件下贮存 30 天,
再以 0.2C 放电至 3.00V 所放出的容量。
Residual capacity
> 90%
剩余容量 > 90%
