Abstract
A solid state electrolyte and method of preparation is provided. The solid state electrolyte includes a plasticized polymer matrix with non-dissolved salt crystals embedded in the polymer matrix and wherein the non-dissolved crystals are suitable for dissolving ions in the plasticized polymer. The method of preparation includes dissolving a plasticizer and a polymer matrix in an organic solvent to obtain a plasticized polymer matrix; and mixing the salt crystals with the plasticized polymer matrix, wherein the weight ratio of salt crystals versus plasticizer and polymer matrix and organic solvent is above saturation concentration such that non-dissolved salt crystals are embedded in the plasticized polymer matrix.
