Anode active material layer and solid-state battery

Abstract

The anode active material layer of the present disclosure includes a lithium alloy represented by the general formula Li—X at a depth of discharge of 80%, where X is Mg, Ag, or a combination thereof. In the anode active material layer of the present disclosure, Li in the lithium alloy has a crystallinity of 8.0% or less, as determined by XRD analysis. The crystallinity is defined by Equation (1): scattering intensity from crystalline phase/(scattering intensity from crystalline phase+scattering intensity from amorphous phase). The solid-state battery of the present disclosure includes the anode active material layer of the present disclosure, a solid electrolyte layer, and a cathode active material layer in this order.
