Abstract:
Provided is an anode material for a secondary battery which reduces and inhibits swelling of a high-capacity silicon-containing alloy material to realize excellent charge/discharge cycle characteristics. The anode material includes alloy particles containing a transition metal which has electron conductivity, is difficult to react with lithium atoms and is at least one selected from the group of metals that belong to transition metals, and silicon, wherein the alloy particles include amorphous silicon, and silicide microcrystals formed by silicon and the transition metal, and the silicide microcrystals are scattered in amorphous silicon.
