Abstract
Provided are an anode mixture configured to provide excellent cycle characteristics when used in an all-solid-state lithium ion secondary battery, an anode containing the anode mixture, and an all-solid-state lithium ion secondary battery containing the anode. Disclosed is an anode mixture for an all-solid-state lithium ion secondary battery, wherein the anode mixture contains an anode active material, a solid electrolyte and an electroconductive material; wherein the anode active material contains at least one active material selected from the group consisting of a metal that is able to form an alloy with Li and an oxide of the metal; and wherein a value obtained by dividing, by a BET specific surface area (m2/g) of the solid electrolyte, a volume percentage (%) of the electroconductive material when a volume of the anode mixture is determined as 100 volume %, is 0.09 or more and 1.61 or less.
