ABSTRACT:
A structure comprising a pair of electrode sheets and an electrolyte sheet, the latter being sandwiched in between the former, wherein each of the pair of electrode sheets comprises a mixture comprising an insulating elastomer and an electrode active substance powder and/or an inorganic solid electrolyte powder, in which mixture the electrode active substance powder and/or the inorganic solid electrolyte powder are dispersed in a volume fraction of 75-95% in the insulating elastomer, and said electrolyte sheet comprises a mixture of an inorganic solid electrolyte powder and an insulating elastomer and optionally an electrode active substance powder, in which mixture the inorganic solid electrolyte powder and optionally the electrode active substance powder are dispersed in a volume fraction of 55-95% in the insulating elastomer. Each of said electrode sheet and said electrolyte sheet may further comprise a reticulate material sheet, the openions of which are filled with the mixture. The structure is excellent in ion-conductivity, processability, productivity, storage stability and flexibility and enables one to make solid electrolyte cells, solid electric double layer capacitors and solid electrochromic display thinner and larger in area.
