Synergistic Enhancement of CoMoO4@Ni(OH)2 Electrode Materials for High Performance Capacitors

Abstract

Electrode materials with excellent electrochemical performance have been ascribed to the significant for energy storage devices. Nanostructures of metal oxides have attracted much attention in the field of supercapacitors because of their rapid charge transport processes. In this work, we prepared CoMoO4@Ni(OH)2 nanowire through a simple hydrothermal methods. The as-fabricated product exhibits a specific capacitance of 1026 Fg−1 at 1 Ag−1. In addition, the samples exhibited a good capacitance retention of 83% after 10000 cycles. This superior electrochemical performance can be ascribed to the unique spatial structure, demonstrating the potential application in next generation micro/nanodevices.
