摘要: Abstract Rational design and synthesis of high performance active materials is one the most challenging tasks in supercapacitors. Herein, a new three-dimensional (3D) reduced graphene oxide (RGO)/carbon nanospheres (CNS)/polyaniline (PANI) ternary nanocomposites were prepared facilely applied as supercapacitor electrode materials. The as-prepared RGO/CNS/PANI characterized by field-emission scanning electron microscopy (FESEM), Fourier transform infrared (FT-IR) spectra X-ray powder diffraction (XRD), respectively. An enhanced specific capacitance was demonstrated compared with other binary RGO/PANI, RGO/CNS pure RGO or PANI. exhibited 583 F g −1 at current density 1 A g excellent cyclic stability 86% its initial large 10 A g after 1000 charge/discharge cycles. In addition, rate capability (72% capacity retention from 1 to ) obtained due synergistic effects results indicated that could be promising material for electrodes.
