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 structures (II) and (III), in which R4 through R8, x2, x3, y2, y3, z2 and z3 are as defined herein. Also provided are conductive, composition containing these novel polymers, particularly film composition, and batteries formulated with such films.
Nouveaux électrolytes polymères conducteurs mono-ioniques (SPE). Un premier groupe de polymères est constitué de polysiloxanes avec substitution par des chaînes latérales de poly(oxyde d'alkylène) possédant des espèces ioniques associées; un second groupe de copolymères renferme des unités de structures (II) et (III), dans lesquelles R4 à R8, x2, x3, y2, y3, z2 et z3 sont définis ici. L'invention présente également une composition conductrice à base de ces nouveaux polymères, notamment une composition pour pellicules, ainsi que des piles conçues à l'aide de ces pellicules.
