Abstract: This work explores facile synthesis of heterogeneous Si/MoSi2 nanocomposites via a one-step magnesiothermic reduction. MoSi2 serves as a highly electrically conductive nanoparticle that has several advantages of electrochemical properties, which is formed through the absorption of local heat accumulation generated by magnesiothermic reduction. As a result, the Si/MoSi2 nanocomposites exhibit excellent electrochemical performance, showing initial charge capacity of 1933.9 mA h g-1 at a rate of 0.2 C and retaining 85.2% after 150 cycles. This work using local heat accumulation generated by magnesiothermic reduction demonstrates a large-scale method for producing high-performance Si-based anode materials, which could provide referential significances for other materials.
