Patent ID: 10069171

Abstract:
Disclosed is a method for manufacturing an all-solid-state lithium ion battery in which a laminated battery is coated with a thermosetting resin, capable of preventing the thermosetting resin from cracking due to charge and discharge of the all-solid-state lithium ion battery after the battery is coated with the thermosetting resin, the method including a first step of laminating a cathode layer, a solid electrolyte layer and an anode layer to form a laminated battery having both end faces in a lamination direction and side faces, a second step of charging the laminated battery until the laminated battery has 100% to 112% of state of charge, a third step of coating at least the side faces of the laminated battery that is charged with a thermosetting resin in an uncured state, and a fourth step of heating to cure the thermosetting resin.
