METHOD FOR PRODUCING SOLID-STATE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a perfect solid-state battery having low internal resistance and high capacity.

SOLUTION: The method for producing the solid-state battery includes the steps of: obtaining active material slurry; obtaining solid electrolyte slurry; obtaining current collector slurry; forming an active material green sheet and a solid electrolyte green sheet; forming a green sheet group by laminating the solid electrolyte green sheet on one surface of the active material green sheet to form a first green sheet group, forming a current collector green sheet layer on the other surface of the active material green sheet with the current collector slurry to form a second green sheet group; heating the second green sheet group at 200-400°C in an oxidizing atmosphere; and baking the second green sheet group heated in the heating step at the baking temperature higher than the heating temperature in the heating step in a low oxygen atmosphere to obtain a laminate.
