摘要
Abstract
Fe2O3 nanoparticles on reduced grapheme oxide (RGO) sheets were successfully synthesized via hydro⁃thermal route for lithium ion battery applications. Selective growth of Fe2O3 nanoparticles on RGO sheets allowed for the electrically insulating Fe2O3 nanoparticles to be wired up to a current collector through the underlying conducting graphene network. The Fe2O3 nano-particles formed on RGO at 180 ℃ show good rate capability and cycling stability. During the charge and discharge process with different current density, the initial discharge ca⁃pacity was 1023.6 mAh/g (current density: 40 mA/g). When the current density increased to 800 mA/g, the dis⁃charge capacity still retained at 406.6 mAh/g, higher than the theory capacity of grapheme~372 mAh/g, and the capacity retained stable in other relative high current density. The Fe2O3/RGO hybrid could be a promising can⁃didate material for a high-capacity, low-cost, and environmentally friendly anode for lithium ion batteries.关键词
