Abstract: 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.

Abstract: A rechargeable battery. A non-coating portion of an electrode plate, a coating portion of another electrode plate corresponding to the non-coating portion, and a separator are separated from each other through an insulating member to prevent a burr generated at the non-coating portion of the electrode plate from damaging the separator. Thus, the thickness of the separator can be reduced to improve battery capacity and reduce manufacturing costs.
