Document Type and Number:
Japanese Patent JP7077923
Kind Code:
B2
Abstract:
Provided is an anode configured to increase the ion conductivity of an anode layer and suppress a decrease in the energy density of the anode layer. Disclosed is an anode, wherein the anode is an anode comprising an anode layer for all-solid-state batteries; wherein the anode layer comprises an anode active material, a solid electrolyte and an ionic liquid; wherein the anode layer comprises at least one Si-based material selected from the group consisting of elemental Si and Si alloy as the anode active material; and wherein the ionic liquid is a solvated ionic liquid containing, in molar ratio, 1.5 mol or more of lithium bis(fluorosulfonyl)imide with respect to 1 mol of tetraglyme, or the ionic liquid is a solvated ionic liquid containing, in molar ratio, 2.0 mol or more of lithium bis(trifluoromethanesulfonyl)imide with respect to 1 mol of tetraglyme.
