Constant Humidity and Temperature Characteristics Test

Under the temperature of 20±5℃,after charging the cell with 600mA(0.2C5),then put the cell into the constant temperature and humidity oven with 40±2℃ and90~95% for 48h,then store the cells at RTfor2hrs,and discharge the cells with 3000mA(1.0C5)to 2.0volts.

The cell has no obvious deformation, leakage,rust, smoking and explosion. Discharge time ≥36min
