Abstract

Provided is an all-solid-state battery that utilizes a precipitation-dissolution reaction of metallic lithium as a reaction of a negative electrode. The all-solid-state battery has a negative electrode current collector, a Li storage layer containing a fibrous carbon material and a resin, a metal M layer capable of being alloyed with lithium, a solid electrolyte layer, and a positive electrode layer in this order.

Claims (12)

1. A battery that utilizes a precipitation-dissolution reaction of metallic lithium as a reaction of a negative electrode, the battery comprising, in the following order:

a negative electrode current collector;

a Li storage layer containing a fibrous carbon material and a resin;

a negative electrode active material;

an electrolyte layer; and

a positive electrode layer, wherein

the electrolyte layer includes a solid electrolyte layer, and

the negative electrode active material is a Li-M alloy layer containing an alloy of lithium and a metal M.

2. The battery according to claim 1 , wherein the metal M is metallic magnesium.

3. The battery according to claim 1 , wherein a thickness of the Li storage layer is 3 μm or more and 33 μm or less.

4. The battery according to claim 1 , wherein a proportion of a lithium element in the Li-M alloy is 30.0 atomic % or higher and 99.8 atomic % or lower in a state where the battery is fully charged.

5. The battery according to claim 1 , wherein the Li storage layer does not comprise graphite.
