After standard charging, the battery is put into a constant humidity box
with a temperature of 40±2℃ and a relative humidity of 90%~95% to be
stored for 48h. The battery is removed and stored for 2 hours at an
ambient temperature of 23℃±2℃ to check its appearance. Then it is
discharged at a current of 0.2A until reaching cut-off voltage of 3.0V
电池标准充电后放入温度 40±2℃、相对湿度(90%~95%)的恒湿

After battery standard charging, 8KV is used to conduct contact
discharge at the battery. Battery is continuously discharge for 10 times,
with an interval of 1s. 12KV is used to conduct air discharge on the
weak insulation position of the battery. Battery is continuously discharge
for 10 times, with an interval of 1s.电池标准充电后,使用 8KV 对电池
的每个金属接触点进行接触放电;连续进行 10 次放电,每次放电间
隔时间为 1s。继续使用 12KV 对电池较薄弱的绝缘位置进行空气放

After standard charging, the battery is stored for 2h, and have
thickness measured. Under the condition of 70℃±2℃, the battery
is stored for 16h. Then, the battery was taken out to be stored for
2h. Battery thickness is measured. Finally, the battery is charge
and discharge at 0.2c current for 1 time. Recording discharge
Swelling rate≦8%, the
discharge time of recovered
capacity> 4.75h. No obvious
difference on battery surface before
and after test.
