Abstract
Graphene/VO2 hybrid materials are prepared by one-step simultaneous hydrothermal reduction technology. The prepared graphene (1.0)/VO2 hybrid material shows a specific capacitances of 225 F gâ1 in 0.5 mol Lâ1 K2SO4 solution. Furthermore, an asymmetric electrochemical capacitor with graphene (1.0)/VO2 as a positive electrode and graphene as a negative electrode is assembled, and it can work in a cell voltage of 1.7 V and show excellent capacitive property.
