Abstract
A charging and discharging method for a lithium secondary battery is provided, wherein, while charging or discharging the lithium secondary battery using a constant current, the charge current or allowable discharge current is modified by measuring the internal resistance of the lithium secondary battery. In the charging and discharging method for a lithium secondary battery according to the present disclosure, the charging time and charge capacity, or the discharge current amount and discharge capacity, may be appropriately harmonized, and thus the method may be usefully used as a charging method and a discharging method for a lithium secondary battery.
