Abstract
Rational design of composite with other electroactive materials can effectively improve the supercapacitive performances through the modulation of electronic structure and conductivity of the hybrid material. In this work, core-shell structured Ni3S2@VO2 nanorods on the nickel foam are prepared through a one-pot hydrothermal method. The addition of VO2 effectively reduces the charge transfer resistance and thus enhances the electrochemical conductivity. The nickel foam provides a platform for the in situ dispersive growth of Ni3S2@VO2 as well as a
