A method of making a composite compound includes oxidation of an alloy, reaction of stabilized lithium metal powder with tin oxide and silicon oxide, and reaction of an inorganic salt of lithium with a tin and silicon-containing compound. [Effects] Tin and lithium, silicon and lithium, or a composite compound of tin, silicon, and lithium, having tin and silicon nano-dispersed in a lithium-containing matrix, are electrode materials for use with rechargeable batteries, particularly Can be used as anode material.
