A supercapacitor is a new type of energy storage device that stores charges based on the electric double layers within electrode/electrolyte interfaces. Due to their good electron conductivity, high synthetic stability and accessible explicit surface areas, carbon materials are the most commonly used electrode materials for electrochemical double layer capacitors, including activated carbon, graphene, carbon nanotubes and mesoporous carbon. However, the low energy density of carbon materials has not been able to meet the demand of high-performance supercapacitor. In this study, we prepared molybdenum oxide–carbon nanotube (MoO-CNT) hybrid materials in the presence of thiolated CNTs by the sol–gel method. The electrochemical performance of MoO-CNT as an electrode material in supercapacitor was evaluated with the cyclic voltammetry. |
