锂离子电池电极材料性能可控制性研究

An enormous growth in portable electronic devices such as cellular phones and laptop computers etc. have led to increasing demand for compact lightweight batteries with high energy density and power capacity. The research purpose in this project is to increase the designation of properties for cathode materials of lithium ion batteries . The research work included theoretical analysis and experiment research work. Basically the relation between the microstructure and electrical properties for cathode materials is the mainly research works. The theoretical work will study and analysis the influence of electrical properties. At the same time the synthesis of cathode materials in microwave , which include solid chemical reaction mechanism, processing method, and heating principle, would be used as an new way to obtain spinal structure for Li-Mn-O materials system. The XRD, XPS and SEM ect. methods will be employed to examine the microstructure and chemical composition of the reaction products.
