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. |
