Facile synthesis of graphene supported FeSn sub(2) nanocrystals with enhanced Li-storage capability

A novel type of graphene supported tin-based alloy, i.e.graphene supported FeSn sub(2) nanocrystals (G-FeSn sub(2) nanohybrid), has been designed and synthesized through a chemical reduction route in a polyol system. When examined as an anode material for lithium-ion batteries (LIBs), the as-synthes...

Zusammenfassung:A novel type of graphene supported tin-based alloy, i.e.graphene supported FeSn sub(2) nanocrystals (G-FeSn sub(2) nanohybrid), has been designed and synthesized through a chemical reduction route in a polyol system. When examined as an anode material for lithium-ion batteries (LIBs), the as-synthesized G-FeSn sub(2) nanohybrid displays markedly enhanced Li-storage capabilities in terms of specific capacities and cycling stability compared with bare FeSn sub(2) nanocrystals.
