英文摘要: For the time being, as one kind of new material Co-Al complex oxide with self-assembled core-shell structure was synthesized in our lab firstly. By using materials design theories and methods, the new material will be investigated on the formation mechanism of its special morphology. The research will focus on the quantitative relationship between the electrochemical performance (specific capacitance and decay rate) and main factors including chemical composition (atoms type and ratio in the complex oxides), structure, morphology and synthetic conditions, etc. The quantitative relationship will be used to guide the theoretical design, controllable synthesis and electrochemical performance prediction and optimization of such materials. The new materials are expected as the research and development object of the supercapacitor cathode materials. This research subject involves in the basic problems important for the development of new materials. The research methods and results will be helpful in the controllable preparation and performance optimization of other new materials.
