METHOD FOR MANUFACTURING ELECTRODE COMPOSITE BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an electrode composite body that can be suitably used for a lithium battery and provide a lithium battery high in output and high in capacity.SOLUTION: A method for manufacturing an electrode composite body includes the steps of: compression-molding a formation material including a particle-like lithium complex oxide and performing heat treatment at a temperature condition of 850°C or above and less than a melting point of the used lithium complex oxide to obtain a porous active material compact; coating a liquid body containing a formation material of an inorganic solid electrolyte on the surface of the active material compact including the inner part of pores of the active material compact to perform heat treatment and forming a solid electrolyte layer; and bonding a collector to the active material compact exposed from the solid electrolyte layer.
