FeSn2–TiC nanocomposite alloy anodes for lithium-ion batteries have been synthesized by a mechanochemical process involving high-energy mechanical milling of Fe/Ti, Ti/Sn, and carbon black. Characterization of the nanocomposites formed with x-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) reveals that this alloy is composed of crystalline nanoparticles of FeSn2 dispersed in a matrix of TiC. The FeSn2–TiC alloy shows an initial gravimetric capacity of 511 mAh g−1 (1073 mAh cm−3) with a first-cycle coulombic efficiency of 77% and a tap density of 2.1 g cm−3. The TiC buffer matrix in the nanocomposite anode accommodates the large volume change occurring during the charge–discharge process and leads to good cyclability compared to similar Sn-based anodes.
