摘要
Compositing metal oxides with nanostructured carbon or conductive polymer supports has been regarded as a compelling way to develop electrode materials with enhanced energy density as well as large power in supercapacitors.Yet,the corresponding cycling stability is still greatly limited due to the intrinsic dissolution of metal oxide nanostructures during redox processes.Herein,phosphate ions modified Fe_(2)O_(3) nanoparticles composited with hollow carbon nanosheet arrays have been synthesized as desirable electrodes with both significantly expanded lifespan and high pseudocapacitance.
