3 Electrical Characteristics

No Item Criteria Testing method
5.1 1C discharge performance Retention capacity≥95%

Charge the cell at method 4.2 at Normal temperature; discharge it at 1C to cut-off voltage(Initial temperature

);And then charge it at method 4.2 , discharge it at 1C to the cut-off voltage again.

5.2 30C continuous discharge capacity at normal temperature

Retention capacity ≥85%,Surface temperature

≤70℃

Rested the cell at least 1h after it is full charged at 25℃±5℃,then discharge it at 30C to the cut-off voltage 2.0V.
5.3 Large current performance at normal temperature

Load voltage within

10S≥2.05V

Rest the cell at least 1h after it is full charged at 25℃±5℃,then test it according to the requirements:Discharge current =60C 10S,Load voltage within 10S ≥2.05V
5.4

20C Continuous discharge current performance at low temperature

(0℃)
