Abstract
A solid electrolyte composition comprising the following components: (i) an organic polymer comprising a polymeric backbone and pendant groups, wherein at least a portion of the pendant groups contain an anionic group associated with a first metal ion; (ii) a solvent homogeneously incorporated in the polymer to result in a polymer gel system; and (iii) a metal salt dissolved in the solvent in a molar concentration of 0.05 M to 1.5 M and containing a second metal ion associated with an anion, provided that the first and second metal ions are the same. Also described herein are solid-state batteries comprising: a) an anode; (b) a cathode; and (c) the solid electrolyte composition described above.
