英文摘要： This project is aimed at synthesizing oxides/carbon composite lithium battery electrode materials by synchronous chemical routes. Solid state reactions in the autoclave will be established to obtain the oxides/carbon composite electrode materials synchronously, in which the oxygen pressure and the additives shall be controlled. For example, a thermal decomposition of organic transition metal complex can be used to simultaneously obtain the oxides and carbon in nanosize. Solvothermal synthesis will also be developed to the synthesis of oxides/carbon composite electrode materials. And in this project, we will pay special attention to the synthesis of oxides electrode materials and the composition of carbon by thermal decomposition synchronously. It will be available for the formation of the oxide phases and the carbon materials by controlling the reaction conditions in the autoclave. After studying the half-cell properties of various kinds of oxides/carbon composite lithium battery electrode materials, we try to find the match between these cathodes and anodes using oxides/carbon composites. We wish to achieve 1-3 kinds of full-cells with good performance.
