title: Porous graphene to encapsulate Na(6.24)Fe(4.88)(P2O7)4 as composite cathode materials for Na-ion batteries.
abstract: Na6.24Fe4.88(P2O7)4@porous graphene composite is fabricated as a cathode of Na-ion batteries for the first time by a hydrothermally assisted sol-gel process. In comparison to non-porous and pristine composites, the as-prepared material exhibits much higher capacity and better rate performance, which are mainly attributed to the high conductivity and rational porous structure of graphene with a significantly increased diffusion coefficient.
