NbO/NiCo复合纳米颗粒的制备与物性表征

In order to explore the electrochemical performance of niobium oxide based composite as electrode material for supercapacitors, carbon cloth loaded NbO/NiCo composite nanoparticles were prepared by one-step CVD method.The prepared samples were analyzed by XRD and SEM to characterize the structure and morphology of the materials. At the same time, the electrochemical properties of the materials were tested by assembling supercapacitors, and the feasibility of using them as electrode materials for KOH supercapacitors was explored.The results show that the prepared electrode material can provide a specific capacity of 90 mAh/g at a current density of 1 A/g, and can maintain 70% of the initial performance after 1000 charge-discharge cycles.
