Abstract: A composite of silicon and tin is prepared as a negative electrode composition with increased lithium insertion capacity and durability for use with a metal current collector in cells of a lithium-ion battery. This electrode material is formed such that the silicon is present as a distinct amorphous phase in a matrix phase of crystalline tin. While the tin phase provides electron conductivity, both phases accommodate the insertion and extraction of lithium in the operation of the cell and both phases interact in minimizing mechanical damage to the material as the cell experiences repeated charge and discharge cycles. In general, roughly equal atomic proportions of the tin and silicon are used in forming the phase separated composite electrode material.
