| Abstract | Reduced-graphene oxide/molybdenum oxide/polyaniline ternary composites, RGO(MP), for use as electrode materials for high energy density supercapacitors, were firstly synthesized using a one-step method with Mo3O10(C6H8N)2·2H2O and graphene oxide (GO) as precursors. When the mass ratio of Mo3O10(C6H8N)2·2H2O to GO is 8 : 1, the resulting composite RGO(MP)8 shows excellent electrochemical performance with a maximum specific capacitance of 553 F g−1 in 1M H2SO4 and 363 F g−1 in 1 M Na2SO4 at a scan rate of 1 mV s−1. Its energy density reaches 76.8 W h kg−1 at a power density of 276.3 W kg−1, and 28.6 W h kg−1 at a high power density of 10294.3 W kg−1 in H2SO4. While in Na2SO4, the energy density achieves 72.6 W h Kg−1 at a power density of 217.7 W kg−1 and 13.3 W h Kg−1 at power density of 3993.8 W kg−1, respectively. The composite also presents good cycling stability (86.6, 73.4% at 20 mV s−1 after 200 cycles in 1 M H2SO4 and Na2SO4, respectively). |
