Abstract
Polymeric compounds are provided the use of which expedites dissociation of an electrolytic salt. The polymeric compounds have a trivalent boron atom which is a Lewis acid. Transport rates of charge carrier ions can be controlled by trapping counter ions of charge carrier ions in the polymeric chain.
