Abstract
Alloy compositions, lithium ion batteries, and methods of making lithium ion batteries are described. The lithium ion batteries have anodes that contain an alloy composition that includes a) silicon, b) aluminum, c) transition metal, d) tin, and e) a fifth element that contains yttrium, a lanthanide element, an actinide element, or a combination thereof. The alloy composition is a mixture of an amorphous phase that includes silicon and a nanocrystalline phase that includes an intermetallic compound of tin and the fifth element.
