Title: Solid polymer electrolyte composition

Abstract

A polymer electrolyte composition includes a hard polymer segment covalently bound to an ionically-conducting segment, and a salt that includes an element M selected from an alkali metal, an alkaline earth metal, zinc, and aluminum. The hard polymer segment has a glass transition temperature (Tg) greater than or equal to 110° C., or a melting temperature (Tm) greater than 110° C. The ionically-conducting segment has a molecular weight of 800 to 10,000 g/mol. The polymer electrolyte composition has an ionic conductivity for an M ion greater than or equal to 1×10−8 S/cm at 25° C. Methods for the preparation of the polymer electrolyte composition are also provided, as are articles (e.g., electrochemical cells and energy storage devices) that contain the polymer electrolyte composition.
