A graphene–amorphous FePO4 hollow nanosphere hybrid as a cathode material for lithium ion batteries

Abstract

Amorphous FePO₄ hollow nanospheres were directly grown on graphene for use as a cathode material in lithium ion batteries. This hybrid exhibits high rate capability and good cycle stability because of efficient Li⁺ ion diffusion through the thin wall of the hollow nanospheres and fast electron transport through the graphene.
