| 中文摘要 | reduced graphene oxide (rgo)/nickel cobaltite (nico2o4) nanoflake composites were prepared by combining in situ assembling and subsequent thermal treatment. the rgo/nico2o4 composites were characterized by scanning electron microscopy, energy dispersive spectroscopy, transmission electron microscopy, x-ray powder diffraction, raman spectroscopy, x-ray photoelectron spectroscopy, nitrogen adsorption/desorption isotherms and thermogravimetric analysis. cyclic voltammetry and chronopotentiometry measurements were performed to investigate the electrochemical properties of the composites. superior performances were achieved with high specific capacitance of 1693 f g(-1) at 1 a g(-1), good rate capability (67.6% capacity retention at 16 a g(-1)) and long-term cyclability (only 9.2% loss after 2000 cycles). the binary redox couples of ni2+/ni3+ and co2+/co3+, ultrathin nanoflake structure, together with the high electrical conductivity of rgo to the outside current collectors are responsible for the excellent electrochemical performances of the rgo/nico2o4 composite, thus suggesting its potential application as an effective electrode material for supercapacitors.
