ABSTRACT:
An ion conducting polymer composition is described which exhibits electrical conductivities of at least 10.sup.-6 S/cm and has good optical properties and is easily processable. The composition comprises a PEO-based block copolymer and a dissociable lithium salt. The invention also includes a laminate formed from the ion conducting polymer composition, and related methods of forming.
