摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a lithium containing garnet type oxide and a lithium secondary battery having higher battery performance, and a method for manufacturing a solid electrolyte. SOLUTION: In the method for manufacturing the solid electrolyte, inorganic materials (for example, Li 2 CO 3 ) in which a gas is formed by calcining them at a prescribed temperature are mixed and crushed in a solvent, the mixed inorganic materials are temporarily calcined at a temporary calcination temperature higher than a prescribed temperature and lower than a molding-calcination temperature to calcine them after molding, a prescribed additive amount of the inorganic materials are added to the calcined material and mixed and crushed in the solvent, the material to which the inorganic materials are added is temporarily calcined further at the temporary calcination temperature, and the material temporarily recalcined without inputting it into the solvent is molded to a molding body and calcined at the molding-calcination temperature. Thus, in the molding and calcination, volume change or the like is smaller and composition drift is suppressed further. For that reason, the solid electrolyte obtained by this method shows high relative density and conductivity. COPYRIGHT: (C)2010,JPO&INPIT
