Method for producing solid state battery

摘要

A method for producing a solid state battery including the steps of: (a) obtaining an active material slurry; (b) obtaining a solid electrolyte slurry; (c) obtaining a current collector slurry; (d) forming an active material green sheet and a solid electrolyte green sheet; (e) laminating the solid electrolyte green sheet on one surface of the active material green sheet to form a first green sheet group, and forming a current collector green sheet layer on the other surface of the active material green sheet to form a second green sheet group; (f) heating the second green sheet group at not less than 200° C. and not greater than 400° C. in an oxidizing atmosphere; and (g) baking the second green sheet group having heated in the step (f) in a low oxygen atmosphere at a baking temperature higher than the heating temperature in the step (f) to obtain a laminate.
