Novel single-ion conducting polymer electrolytes (SPEs) are provided. A first group of polymers are polysiloxanes substituted with fluorinated poly(alkylene oxide) side chains having associated ionic species, while a second group are copolymers containing mer units having the following structures gh R8, x2, x3, y2, y3, z2, and z3 are as defined herein. Also provided are conductive compositions containing these novel polymers, particularly film compositions, and batteries formulated with such films.
