Abstract

An ionically conductive polymeric binder for a cathode including m repeat units according to formula (I) and n repeat units according to formula (II) wherein R1 is (CH2)x—R3, wherein x is between 1 and 20 and R3 is H or CN; R2 and R5, individually, are C1-C10 alkyl or C2-C10 alkenyl; M is an alkali metal or an alkaline earth metal; the ratio of m to n (m/n) is between 25:1 and 1:25; and m+n is q, wherein q is between 50 and 5000. Also, a cathode including the ionically conductive polymeric binder, and a method of producing the ionically conductive polymeric binder.
