Abstract

Fe₂NiSe₄@holey-graphene (FNS@HG) has been prepared by in situ growth and simultaneous perforation via a carbothermal reaction. The generation of nanoholes on the graphene sheets significantly reduced the diffusion distance of electrolyte ions, enhancing the rate capability of FNS@HG as an anode material for sodium-ion batteries.
