Interface Engineering of Core-Shell Structured Co3O4@Ni(OH)2 Nanowires for Energy Storage Device

For energy storage systems, it is essential to build high performance electrodes. Electrochemical properties of electrode materials have been attributed to important forensic storage facilities. However, the single structured electrode materials exhibited poor conductivity and cycling stability. In this paper, Co3O4/Ni(OH)2 nanowire was prepared by a simple hydrothermal method. The as-manufactured product showed a specific capacitance of 1266 Fg-1 at 1 Ag-1. The as-fabricated Co3O4@Ni(OH2//active carbon device can achieve a maximum energy density of 32.5 Wh kg-1. This superior electrochemical performance can be ascribed to the unique spatial structure, demonstrating the potential application in next generation micro/nanodevices.
