Abstract
The present technology relates to a method for producing a single-ion conducting polymer comprising grafting a thiol functionalized conductor compound onto a polymer compound to obtain the single-ion conducting polymer. In certain embodiments, the thiol functionalized conductor compound can be grafted onto polymers having low Tg which result in single-ion conducting polymers having improved conductivity.
