Abstract
Developing electrode materials with high specific capacitance and excellent stability for energy storage is necessary to solve energy shortage issues. In this work, we prepare ZnCo2O4@CoMoO4 core-shell structures on nickel foam by a simple hydrothermal approach. The as-synthesized products show excellent electrochemical performances. It reveals that the secondary growth of CoMoO4 nanosheets induces many active sites and facilitates rapid ion and electron transmission. In addition, the as-assembled device delivers high energy density, indicating that the as-obtained samples are excellent candidates for future energy storage applications.
