Title:
正極合剤の製造方法、正極の製造方法、及び全固体リチウムイオン二次電池の製造方法
Document Type and Number:
Japanese Patent JP6409794
Kind Code:
B2
Abstract:
A method is provided where an anode of an all-solid-state lithium ion secondary battery is easily doped with lithium and to provide a small resistance at a low battery capacity. The method includes a manufacturing method of a cathode including mixing at least a conductive assistant (C1) and a sulfide solid electrolyte (E1) to obtain a mixture; and mixing at least one cathode active material, a solid electrolyte (E2) and the mixture obtained from the first step to obtain a cathode mixture, wherein an amount of energy added to the sulfide solid electrolyte (E1) is larger than an amount of energy added to the solid electrolyte (E2), and the mixture is a material that releases lithium ions at a potential lower than a potential at which the cathode active material releases and occludes lithium ions. Manufacturing methods for a cathode and an all-solid-state lithium ion secondary battery including the cathode mixture are also disclosed.
