Process Optimization and Capacitance Performance of Ti/RuO2-HfO2 Synthesized by Thermal Decomposition Method
Ti/RuO2-HfO2 composite oxide coating was prepared by thermal decomposition method and the micro-structure of the coating was characterized by XRD.The supercapacitor properties of the coating were studied by cyclic voltammetry and charge-discharge curve.The results show that the addition of Hf is beneficial to the forma-tion of amorphous structures.With the increase of Hf content,the specific capacitance of the electrode increases first and then decreases.When Hf content is 50%,the specific capacitance of the electrode reaches the maximum,and Hf has the effect of promoting electrochemical stability.
