Abstract
Composite compounds of tin and lithium, silicon and lithium, or tin, silicon, and lithium having tin and silicon nano-dispersed in a lithium-containing matrix may be used as electrode materials and particularly anode materials for use with rechargeable batteries. Methods of making the composite compounds include the oxidation of alloys, the reaction of stabilized lithium metal powder with tin and silicon oxides, and the reaction of inorganic salts of lithium with tin and silicon containing compounds.
