Abstract
An overcharge inhibitor is provided which increases an internal resistance of a battery, being electropolymerized by reaction with a positive electrode at a high potential in overcharging. The overcharge inhibitor is produced by using a polymer containing a polymerizable monomer as a repeating unit. The polymerizable monomer has a functional group that is electropolymerized at a potential of 4.3 to 5.5 V based on a lithium metal reference.
