Abstract:
Compositions are described that can provide high energy density active materials for use in negative electrodes of lithium ion batteries. These materials generally comprise silicon and/or tin, and may further comprise carbon and/or zinc as well as other elements in appropriate embodiments. The active materials can have moderate volume changes upon cycling in a lithium ion battery.
