Abstract
The present invention suppresses a decrease in the capacity of a lithium ion battery. A polymer forming agent or a sacrificial reducing agent is added to a nonaqueous electrolytic solution. A voltage is then applied to between a battery container and an anode. Thus, lithium ions can be inserted into the anode to recover the capacity of the battery.
