Dr. Jie Li visited the research group for academic exchange from Helmholtz Institute Ulm,HIU

May 3-4, 2019，At the invitation of Prof. Yang Yong, State Key Laboratory for Physical Chemistry  Physics of Solid Surfaces, Dr. Li Jie visited Xiamen University for academic exchange and Sino-German project cooperation。

  First of all, Dr. Li made an academic report titled "Fluorine-free electrolytes for sustainable green lithium-ion batteries" in College of Chemistry and Chemical Engineering。In her academic report, Dr. Li systematically introduced the history and development of the new-type water electrolyte system, especially the fluorine-free water electrolyte system for green lithium ion battery that can be developed in recent years。The recent research progress of their research group is also described. Through electrochemical tests, it is found that Lippa, a new material, has high conductivity, can expand the voltage window of water system electrolyte, and has stable electrochemical performance.Dr. Li's report is very novel and has won the attention and welcome of the teachers and students in the related research groups of the college. The research has a good application prospect.

Second, Dr Li jieren also represent Germany organized sino-german cooperation project discussion, discussion is focused on using in situ electrochemical method has been established, the solid state electrochemical reaction process of new materials in electrochemical from all the aspects concerned with in situ spectroscopy technology (such as solid nuclear magnetic and X-ray absorption spectrum, etc.), and connecting with the first principles calculation, system of new type material system structure-activity relationship and mechanism analysis, for the development of a new generation of high specific capacity oxide materials and their compatible electrolyte systems provide theoretical guidance and data to support.
