PURPOSE:To provide an all-solid secondary battery which works with a high voltage presents a large capacity and charge/discharge characteristics, and excels in the safety. CONSTITUTION:An all-solid secondary battery is composed of a neg. electrode, highpolymer solid electrolyte, and pos. electrode, wherein the solid electrolyte contains chiefly a highpolymer matrix and a metal salt electrolytic solution and also contains highpolymer and/or surface active agent which are soluble in water and/or polar solvent. Therein the matrix and the electrolytic solution are phase segregated, and the highpolymer and/or surface active agent stabilize co-dispersion of the matrix and electrolytic solution. The pos. electrode assumes a sheet form in which pos. electrode active substance particulates and electron conductor are dispersed in the highpolymer solid electrolyte. Thereby the characteristics of all-solid secondary battery can be enhanced. |
