Electric performance test
Rate discharge performance
After charging at standard 25±2℃, the battery was set aside for 10min and discharged to 2.75v at 0.2c, 0.5c and 1.0c, respectively, for 10min to test the multiplier discharge performance of the battery
Rate discharge 0.2C 0.5C 1.0C
Capacity retention 95% ＞90%
High-and-low temperature performance
The battery is charged under the ambient temperature 25±2℃, and then cool down or heating up to the test temperature within 30 minutes. Before discharging, the battery remains at this temperature for 1 hour. The constant discharge reaches the cut-off voltage of2.75v and the discharge current is 0.2cmA.
Discharge Temperature -20℃(0.2C) 25℃(0.2C) 60℃(0.2C)
Discharge capacity ＞60% 100% ＞100%
After charging the electrical standard, set it aside for 10min, discharge 0.2C mA to 2.75v, set it aside for 10min, repeat the above steps for circulation, 25±2℃,500 times capacity retention rate greater than 80%.
