Abstract
Disclosed herein are multiphase metal anodes useful in non-aqueous batteries. The anodes include at least one active metal and at least one conductive metal.
Claims20
An anode comprising:
- an anode active material, wherein the anode active material is an integrated multiphase metallic foil, wherein the integrated multiphase metallic foil is a rolled foil and wherein the integrated multiphase metallic foil comprises:
- a first metal phase comprising an active metal that alloys with an alkali metal or an alkaline earth metal at a first alloying potential;
- and
- a second metal phase comprising a conductive metal that alloys with the alkali metal or the alkaline earth metal at a second alloying potential, wherein the first alloying potential is greater than the second alloying potential.
1 more element
A method of making an anode, comprising:
- forming a mixed metal precursor comprising an active metal and a conductive metal, and
- rolling the mixed metal precursor to a thickness no greater than 0.05 mm to generate an integrated multiphase metallic foil, wherein the integrated multiphase metallic foil is a rolled foil and wherein the integrated multiphase metallic foil comprises:
- a first metal phase comprising an active metal that alloys with an alkali metal or an alkaline earth metal at a first alloying potential;
- and
- a second metal phase comprising a conductive metal that alloys with the alkali earth metal or the alkaline earth metal at a second alloying potential, wherein the first alloying potential is greater than the second alloying potential.
