ABSTRACT:
A solid electrolyte sheet comprising an ion-conductive inorganic solid electrolyte and an insulating elastomer, wherein the inorganic solid electrolyte powder is uniformly dispersed in the insulating elastomer in a volume fraction of 55-95% and which sheet has a hardness (ASTM A) of 65-96 and a thickness of 10-250 .mu.m, or a solid electrolyte sheet comprising a non-conductive reticulate material and a mixture of an ion-conductive inorganic solid electrolyte powder and an insulating elastomer, in which mixture the solid electrolyte powder is uniformly dispersed in the insulating elastomer in a volume fraction of 55-95%, at least the openings of the reticulate material being filled with said mixture. Said solid electrolyte sheets are superior in ion-conductivity, processability, productivity, storage stability and flexibility and are suitable for use in thin and large electrochemical elements.
