SnSb–TiC–C nanocomposite alloy anodes for lithium-ion batteries have been synthesized by a mechanochemical process involving high-energy mechanical milling of Ti–Sn and Ti–Sb precursors with carbon black. Characterization of the formed nanocomposites using x-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) reveals that these alloys are composed of crystalline nanoparticles of SnSb dispersed in a matrix of crystalline TiC and amorphous carbon. The SnSb–TiC–C alloy shows an initial gravimetric capacity of 769 mAh g−1 (1385 mAh cm−3), an initial coulombic efficiency of 84.9%, and a tap density of 1.8 g cm−3. The buffer matrix of TiC and carbon in the nanocomposite alloy anodes accommodates the large volume change occurring during the charge–discharge process and leads to enhanced cyclability compared to pure SnSb anodes as well as previously published SnSb composites.
