8.1 High Temperature Storage Test

Test method : Cells are charged per 6.1 and stored in a temperature-controlled environment at

60ºC for 1 week. After test, cells are discharged per 6.2 and cycled per 6.4 for 3 cycles to obtain recovered capacity.

Criteria : No leakage, Capacity recovery rate ≥ 80 % 8.2 High Temperature and High Humidity Test

Test method : Cells are charged per 6.1 and stored at 60ºC (95% RH) for 168 hours. After test,

cells are discharged per 6.2 and cycled per 6.4 for 3 cycles to obtain recovered capacity.

Criteria : No leakage, No rust, Capacity recovery rate ≥ 80 % 8.3 Thermal Shock Test

Test method : 65ºC (8Hrs) ← 3hrs → -20ºC (8Hrs) for 8 cycles with cells charged per 6.1.

After test, cells are discharged per 6.2 and cycled per 6.4 for 3 cycles to obtain recovered capacity.

Criteria : No leakage, Capacity recovery rate ≥ 80 % 9.1 Abnormal Charge Test

Test method : Cells are discharged per 6.2, then charged at constant current of 7200mA and

constant voltage of 4.2V while tapering the charge current. Charging is continued for 48 hours (Per UL1642).

Criteria : No rupture, No fire 9.2 External Short-circuiting Test

Test method : Cells are charged per 6.1, and the positive and negative terminal is connected by

a 100m -wire for 1 hour (Per UL1642).

Criteria : No rupture, No fire 9.3 Overdischarge Test

Test method : Cells are discharged at constant current of 480mA to 250% of the minimum

capacity (Per UL1642).

Criteria : No rupture, No fire
