Abstract:
1. A method of manufacturing an electrode body which comprises an electrode layer and an electrolyte layer disposed on the electrode layer, the method comprising: an electrode layer forming step of dispersing at least an active material releasing or absorbing and releasing a metal ion, an electrolyte having conductivity for the metal ion, and a binder into a solvent, to prepare an electrode slurry, and applying the electrode slurry onto a base material, thereby forming the electrode layer containing the binder; an electrolyte layer forming step of dispersing at least an electrolyte having conductivity for the metal ion into a solvent to prepare an electrolyte slurry, and applying the electrolyte slurry onto a surface of the electrode layer, wherein at least some of the binder contained in the electrode layer absorbs the solvent contained in the electrolyte slurry and expands and one end of some of the binder that has expanded is disposed in the electrode layer and the other end thereof is disposed in the electrolyte slurry, thereby forming the electrolyte layer on the surface of the electrode layer; a step of removing the solvent contained in the electrode layer; and a step of removing the solvent contained in the electrolyte layer, wherein the electrolyte is an oxide solid electrolyte or a sulfide solid electrolyte, and the binder is butylene rubber.
