发明名称 Method of testing cycle life of lithium rechargeable battery
摘要 The provided are two test methods for the cycle life test of a lithium rechargeable battery, which measures charge/discharge capacity by repeating charging and discharging lithium rechargeable battery. In one method, a constant current-constant voltage of charge rate of 1.5C and 4.2V, and a cut-off current of 0.1C are set to charge the battery, and a discharge rate of 1.0C and a cut-off voltage of 3.0V are set to discharge the battery, and there is no rest period between the charging and discharging. In another method, a constant current-constant voltage charge condition of charge rate of 1.0C and 4.2V, and a cut-off current of 0.1C are set to charge the battery, and a discharge rate of 1.3C and a cut-off voltage of 3.3V are set to discharge the battery, and there is no rest period between the charging and discharging. The present invention is appropriate to the cycle life test method of 500 cycles.
