| 英文摘要 | Fe3o4@carbon nanosheet composites were synthesized using ammonium ferric citrate as the fe3o4/carbon precursor and graphene oxide as the structure-directing agent under a hydrothermal process. the surface chemical compositions, pore structures, and morphology of the composite were analyzed and characterized by nitrogen adsorption isotherms, tg analysis, ft-ir, x-ray photoelectron energy spectrum, transmission electron microscopy, and scanning electron microscopy. the composites showed excellent specific capacitance of 586 f/g 340 f/g at 0.5 a/g and 10 a/g. the all-solid-state asymmetric supercapacitor device assembled using carbon nanosheets in situ embedded fe3o4 composite and porous carbon showed a largest energy density of 18.3 wh/kg at power density of 351 w/kg in koh/pva gel electrolyte. the synergism of high special surface to volume ratio, mesoporous structure, graphene-based conduction paths, and fe3o4 nanoparticles provided a high surface area of ion-accessibility, high electric conductivity, and the utmost utilization of fe3o4 and resulted in excellent specific capacitance, outstanding rate capability and cycling life as all-solid-state supercapacitor electrodes. |
