MANUFACTURING METHOD FOR ALL-SOLID BATTERY

PROBLEM TO BE SOLVED: To provide a manufacturing method for an all-solid battery enabling thinning and enlargement of a lithium-ion battery that is needed for providing a lithium-ion battery with improved performance and increased capacity and capable of preventing short-cut between both electrode material layers.SOLUTION: A manufacturing method for an all-solid battery in which a collector is arranged on each of both surfaces of a laminate formed by arranging a solid electrolyte layer between a positive electrode layer and a negative electrode layer, comprises a step of laminating a solid electrolyte 13 on a positive electrode mixture 12 comprising a positive electrode active material and a solid electrolyte, followed by pressure molding to obtain a positive electrode member 14, a step of laminating a solid electrolyte 23 on a negative electrode mixture 22 comprising a negative electrode active material and a solid electrolyte, followed by pressure molding to obtain a negative electrode member 24, and a step of performing pressure molding to the positive electrode member 14 and the negative electrode member 24 obtained in the above-mentioned steps by combining the solid electrolytes 13 and 23 each other, to manufacture the above-mentioned laminate.
