报告题目: Structure Design and Property Enhancement of Lithium Battery Electrodes

简历:

Shi-Gang Sun obtained his Bachelor of Science from Xiamen University, China, in 1982, Doctorat d’Etat (Docteur ès Sciences Physiques) from the Université Pierre et Marie Curie (Paris VI), France, in 1986. After one-year post-doctoral research in the Laboratoire d’Electrochimie Interfaciale du CNRS, France, he returned to China by the end of 1987, and served as associate professor and later full professor in 1991 at the Department of Chemistry of Xiamen University till now. Prof. Sun has been elected Academician of Chinese Academy of Sciences, fellow of International Society of Electrochemistry (ISE) and fellow of Royal Society of Chemistry (RSC).

摘要:

The properties of lithium batteries depend strongly on the structure of electrode materials and interfacial processes involved in lithium storage reactions. The structure of electrode materials, especially the surface structure, determines the density of active sites/channels for Li intercalation or conversion, and is therefore a crucial factor of controlling the transport kinetics thus the rate performance of the battery. On the other hand, to better understand the interfacial processes is significant in designing and engineering the electrode materials and battery systems.
This communication reports our recent progresses on study focusing on tuning the structure and performances of electrode materials of lithium battery. Different materials including nanostructured metal oxides, habit-tuned LNMO nanoplates, NCM hexagonal nanobricks, graphene-based sulfur and RuO2/MnO2 nanorods were designed and control-synthesized, and served as electrodes in lithium ion battery, lithium-sulfur battery and lithium-air battery. The results demonstrated clearly the significant enhancement of electrochemical performances of specific capacity, cycleability and rate property of the as-prepared electrode materials with well-defined structure. Besides the active materials of electrode, environmental friend and multi-functional binder for the next generation lithium-ion batteries with high energy density has been developed and applied in both anode and cathode of lithium ion batteries
