Abstract
To provide an anode material which is resistant to deactivation even when it is exposed to an oxygen-containing gas atmosphere, and a solid-state battery using the same. An anode material for solid-state batteries that use a precipitation-dissolution reaction of lithium metal as an anode reaction, wherein the anode material is a multiphase alloy comprising a Li single phase and a Li-M alloy phase; wherein M of the Li-M alloy phase is at least one metal selected from the group consisting of Al, In and Zn; and wherein an amount of the M in the multiphase alloy is 0.90% by mass or more and 21.00% by mass or less.
Claims5
An anode material for solid-state batteries that use a precipitation-dissolution reaction of lithium metal as an anode reaction,
- wherein the anode material is a multiphase alloy comprising a Li single phase and a Li-M alloy phase;
- wherein M of the Li-M alloy phase is at least one metal selected from the group consisting of Al, In and Zn;
- and
- wherein an amount of the M in the multiphase alloy is 0.90% by mass or more and 21.00% by mass or less.
A solid-state battery that uses a precipitation-dissolution reaction of lithium metal as an anode reaction, the solid-state battery comprising a cathode comprising a cathode layer, an anode comprising an anode current collector and an anode layer, and a solid electrolyte layer disposed between the cathode layer and the anode layer,
- wherein the anode layer comprises an anode material that is a multiphase alloy comprising a Li single phase and a Li-M alloy phase;
- wherein M of the Li-M alloy phase is at least one metal selected from the group consisting of Al and In and Zn;
- and
- wherein an amount of the M in the multiphase alloy is 0.90% by mass or more and 21.00% by mass or less when the solid-state battery is fully charged.
