Abstract
A copolymer for constituting a polymer electrolyte for a solid-electrolyte lithium or sodium cell. A polymer electrolyte that is usable in combination with high-voltage cathode active materials and makes it possible to provide solid-electrolyte lithium or sodium cells and/or batteries having a high energy density that is sufficient even for use in electricity-based vehicles, the copolymer encompasses at least two ion-conductive polymers, the copolymer encompassing at least one polymer polymerized by ring-opening polymerization of at least one lactone and/or of at least one lactide and/or of at least one cyclic carbonate and/or of at least one cyclic carbamate and/or of at least one lactam and/or of at least one epoxide, and/or at least one polymer polymerized by radical polymerization of acrylonitrile and/or of at least one acrylonitrile derivative; and encompasses at least one polyacrylate having at least one repeating unit.
