MANUFACTURING METHOD OF ELECTRODE ASSEMBLY, ELECTRODE ASSEMBLY, AND BATTERY

摘要

A manufacturing method of an electrode assembly includes: forming an active material compact containing a lithium double oxide and having a plurality of voids; forming a first solid electrolyte in the plurality of voids; impregnating a precursor solution of a second amorphous solid electrolyte conducting lithium ions with an active material compact in which the first solid electrolyte is formed; and performing heat treatment of the active material compact with which the precursor solution is impregnated and forming a second solid electrolyte in the plurality of voids.

1. A manufacturing method of an electrode assembly comprising:
forming an active material compact having a plurality of voids; impregnating a first solid electrolyte precursor with the active material compact; forming a first assembly by performing heat treatment for the active material compact with which the first solid electrolyte precursor is impregnated; impregnating a second solid electrolyte precursor with the first assembly; and forming a second assembly by performing heat treatment for the first assembly with which the second solid electrolyte precursor is impregnated, wherein the second solid electrolyte precursor is amorphous at a room temperature, and the forming of the second assembly is a process of drying a solvent of the second solid electrolyte precursor, and a temperature of the heat treatment in the forming of the second assembly is lower than a temperature of the heat treatment in the forming of the first assembly.
