The research group has engaged in the development of new electrode materials, electrode interface regulation, in-situ spectroscopy methods and electrochemical reaction mechanism. At present, our research group has developed a systematic theoretical system in the structural design and electrochemical performance regulation of various electrode materials and solid electrolytes; different kinds of advanced functional electrolytes to improve the electrochemical performance and safety of batteries; many high specific energy storage systems, including lithium metal/lithium-free anodes, all-solid-state batteries, etc.; a variety of in-situ characterization techniques. In recent years, the research and production of lithium-ion batteries have attracted much attention around the world. However, the energy density, cycle life and safety of energy storage batteries still cannot meet the requirements of today's social development.
With the wish to settle down these issues, the main topic of our research group is on electrochemical energy conversion and storage system, especially on the new electrode materials, interfacial properties and in-situ characterization techniques of lithium-ion batteries and other rechargeable batteries. Currently, the basic research of our research group includes:
