文摘

Ultrafine nano-Si was prepared via a NaCl-assisted magnesiothermic reduction. Heat scavenger NaCl promotes the formation of silicon nanograins of 5–10 nm. Raw material is highly cheap and scalable silicate, promising its practicability. Graphene nanosheets improve the Li-storage properties of nano-Si as anode for LIBs. Final nano-Si/rGO exhibits high reversible capacity and superior rate capability.
