PROBLEM TO BE SOLVED: To provide a solid electrolyte composition material that can implement an excellent binding capacity, an excellent film state when a coating film is formed and a cycle characteristic, a battery electrode sheet using the same, and a method of manufacturing a battery electrode sheet and an all-solid secondary battery.SOLUTION: A solid electrolyte composition for forming an all-solid secondary battery containing a positive electrode active material layer, an inorganic solid electrolyte layer and a negative electrode active material layer forms at least one layer of the positive electrode active layer, the inorganic solid electrolyte layer and the negative electrode active layer. The composition contains inorganic solid electrolyte having electrical conductivity of metal ions belonging to the first group or second group of the periodic table, polymer particles and dispersion medium. The dispersion medium contains at least one kind of solvent dissolving the polymer particles, and at least one kind of solvent which does not dissolve the polymer particles. A battery electrode sheet and an all-solid secondary battery that use the solid electrolyte composition, and a method of manufacturing the battery electrode sheet and the all-solid secondary battery are provided.SELECTED DRAWING: Figure 1 |
