Abstract
Alloy compositions are described for use in anodes of lithium ion batteries. The alloy compositions contain (a) tin, (b) a second element that includes silicon, aluminum, or a combination thereof, (c) a third element that includes yttrium, a lanthanide element, an actinide element, or a combination thereof and an optional alkaline earth element, and (d) an optional transition metal. The alloy compositions are amorphous and remain amorphous even after multiple cycles of lithiation and delithiation.
