Abstract: Negative electrode compositions for use in a lithium-ion electrochemical cell are provided that has the formula, SixSnqMyCz, wherein q, x, y, and z represent mole fractions, q, x, and z are greater than zero and M is one or more transition metals. The provided electrode compositions are amorphous and can be made by sputtering or ball milling. Typically, 0.50≦x≦0.83, 0.02≦y≦0.10, 0.25≦z≦0.35, and 0.02≦q≦0.05. Electrodes made using the provided electrode compositions can include a binder than can be lithium polyacrylate.
