Abstract
A method of manufacturing an all-solid-state battery includes forming an anode active material layer on surfaces of an anode current collector, forming a first solid electrolyte layer covering exposed surfaces of the anode active material layer to form a symmetrical electrode structure, pressing the structure at a preliminary pressing pressure lower to form an anode, forming a cathode active material layer on a surface of cathode current collectors, the cathode active material layer being smaller than the cathode current collectors, forming a second solid electrolyte layer covering the cathode active material layers and the cathode current collectors to form first and second cathodes, forming a laminate by laminating the cathodes on opposite surfaces of the anode, the second solid electrolyte layers of the cathodes facing the anode, and pressing the laminate at the final pressing pressure.
