英文摘要： The hybrid supercapacitor, which is composed of the anode of electrolytic capacitor and the cathode of electrochemical hybrid supercapacitor, has broad application prospects because its operating voltage is an order of magnitude higher than the ordinary supercapacitor. The main performance parameters of the hybrid supercapacitor are determined by the energy flow allocation in the capacitor, therefore, accurate description of the dynamic characteristics of the energy flow is one of the basic scientific issues.The energy storage physical model of the hybrid supercapacitor, which is based on the energy flow, is modelled firstly in this research project. On the basis of this hybrid supercapacitor model, the impact of the structural parameters of the energy distribution, and the influence law of the electrode material with different ratio, configuration method of energy distribution and even performance parameters are investigated. According to the results of the model analysis, a sample of hybrid supercapacitor with high-performance parameters is in preparation, and then the model is amended after test analysis of the electrochemical workstation. The purpose of this project is to improve the electrical performance and storage density parameter of the supercapacitor, as well as expand the range of applications of su
