Excellent cycling stability and superior rate capability of a graphene–amorphous FePO4 porous nanowire hybrid as a cathode material for sodium ion batteries

Abstract

A porous nanowire material consisting of graphene–amorphous FePO₄ was investigated as an advanced cathode material for sodium ion batteries for large-scale applications. This hybrid cathode material showed excellent cycling performance and superior rate capability, which were attributed to the porous nanowire structure and the existence of graphene.
