Abstract

Sn-based chalcogenide composites (TCC) were synthesized as high-capacity anode materials. SnS formed within TCCs 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.
