PURPOSE:To obtain a solid electrolyte composition having excellent moldability, ionic conductivity, etc., comprising a polyether compound containing ethylene oxide chain and/or propylene oxide chain, an ion exchange layered compound and an ionic substance. CONSTITUTION:(A) A polyether compound having 1,000-5,000,000 average molecular weight obtained by adding ethylene oxide and/or propylene oxide to a polyamine compound in the presence of a catalyst at 100-180 deg.C under 1-10 atmospheric pressure is blended with (B) an ion exchange layered compound (e.g. montmorillonite or zirconium phosphate) and (C) an ionic substance (preferably alkali metal salt) shown by the formula MX (M is metal ion, proton or ammonium ion; X is anion of strong acid) as essential components and ionic conductive powder (e.g. copper ionic conductive solid electrolyte) in an amount not to damage chemical stability to give a solid electrolyte composition. |
