    摘要: When a hole in a separator is clogged, the cycle characteristics of a battery might be lowered and the internal resistance of a battery might be increased to reduce the output. Thus, a means for suppression of or recovery from degradation due to a clogged separator in a battery such as a lithium-ion secondary battery is provided. When reverse pulse current is supplied multiple times during charge, a separator is prevented from being clogged and a voltage increase (increase in internal resistance) during charge is suppressed, so that charge can be normally performed repeatedly.
