▎ 摘　　要

A novel type of graphene supported tin-based alloy, i.e. graphene supported FeSn2 nanocrystals (G-FeSn2 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-FeSn2 nanohybrid displays markedly enhanced Li-storage capabilities in terms of specific capacities and cycling stability compared with bare FeSn2 nanocrystals.
