A new As3Mo8V4/PANi/rGO composite for high performance supercapacitor electrode

Herein, [As2 IIIAsVMo8 VIV4 IVO40]2[CuICu2 II(pz)4]2.9H2O/polyaniline/reduced graphene oxide (pz = pyrazine, abbreviated to As3Mo8V4/PANi/rGO) composite is first assembled, characterized and systematically explored for its supercapacitor performance. As3Mo8V4/PANi/rGO composite shows a exceptional specific capacitance (2351 F g- 1 at 1 A g-1) and outstanding cyclic stability (96.9% after 5000 cycles). The symmetric supercapacitor exhibits high specific capacitance of 1295 F g-1 at 1 A g-1 and excellent energy density of 88.1 Wh kg-1 at power density of 349.6 W kg-1, while maintaining a notable capacitance retention of 85.7% after 5000 cycles at 2 A g-1. The above results confirm the potential application of As3Mo8V4/PANi/rGO composite in energy storage devices.
