Abstract
Metal alloy layers on substrates. The metal-alloy layers (e.g., lithium-metal layers, sodium-metal layers, and magnesium-metal layers) can be disposed on, for example, a solid-state electrolyte material. The metal-alloy layers can be used in, for example, solid-state batteries. A metal alloy layer can be an anode or part of an anode of a solid state battery.
Claims24
A metal-alloy layer comprising:
- a metal-alloy forming a layer disposed on at least a portion of a surface or all of the surfaces between a metal anode comprising lithium, sodium, magnesium, or alloy thereof and a solid-state electrolyte (SSE) material,
- wherein,
- the metal anode is located within pores of the SSE material;
- the metal-alloy has a thickness of 1 nm to 100 nm;
- and
- the metal-alloy comprising a first metal, M1, and a second metal, M2, wherein:
- i) M1 is lithium, sodium, or magnesium;
- ii) M2 is a metal selected from the group consisting of aluminum, gallium, tin, magnesium, zinc, and combinations thereof and/or a metalloid selected from the group consisting of silicon, germanium, and combinations thereof;
- and
- iii) the mol fraction of M2 in the layer is 0.1 to 0.8.
