Sn ‐based chalcogenide composites ( TCC ) were synthesized as high‐capacity anode materials. SnS formed within TCC s is an active center for Li ‐intercalation. Electrochemical cycling shows that the Sn – Ge – S matrix suppresses the volume expansion that can arise from alloying between Sn and Li as well as the grain growth associated with the low melting temperature of Sn . Sn – Ge – S complex phases in an amorphous state can contribute to the high capacity of Sn : Ge – S (6:4 m/m), possibly suppressing the agglomeration and pulverization of Sn .
