Carbon-modified　iron　oxide　metal　frameworks　(MOF),a　highly　porous　nanostructured　Li-ion　battery　material,were　synthesized　via　chemical　route.First,Fe2O3　micro-cubes　were　fabricated　by　calcination　of　Prussian　blue　micro-cubes;　next,amorphous　carbon　thin　films　were　deposited　on　its　porous　surfaces　by　hydro-thermal　method　in　glucose　solution;　and　finally,the　microstructures　and　Li-ion　storage　behavior　of　the　dried　C@Fe2O3　micro-cubes　were　characterized　with　X-ray　diffraction,X-ray　photoelectron　spectroscopy,scanning　electron　microscopy,transmission　electron　microscopy　and　cyclic　voltammetry.The　results　show　that　the　modification　of　carbon　coating　significantly　improves　the　conductivity　and　Li-iron　storage　performance　of　Fe2O3　micro-cubes.To　be　specific,the　discharge　capacity　of　the　porous　C@Fe2O3　micro-cubes　was　up　to　598　mAh/g　after　100　cycles.Moreover,the　volumetric　effect　in　charge/discharge　of　the　C@Fe2O3　micro-cubes　was　markedly　weakened.　©　2019,　Journal　of　Vacuum　Science　and　Technology　Publishing　House.　All　right　reserved.
