Abstract
Provided herein are composite electrolytes that include inorganic conductors and polar polymers. By providing the polar polymers as structures such as microspheres in a suspension in a non-polar solvent, the polar polymers can be used as binders in composites that include sulfide electrolytes. The resulting composites have high room temperature conductivities and good mechanical properties. Also provided are composites that include inorganic conductors and other polymers that are insoluble in non-polar solvents. Also provides methods of forming composite electrolytes using suspensions of polymer microstructures in a processing solvent and the resulting composite electrolytes.
