On October 14, 2024, Zhang Xueqiang, Associate Researcher of the Institute of Frontier and Cross Science of Beijing Institute of Technology, was invited to visit the Institute of New Concept Sensors and Molecular Materials and gave a report titled “Stability Mechanism of Negative Electrode/electrolyte Interface of High Specific energy and Long Cycle Lithium Batteries”.

Zhang Xueqiang introduced four research works by introducing the common problems of the negative electrode/electrolyte interface: designing the lithium-ion solvation layer structure to construct the fluorinated surface in situ, enhancing the mechanical stability of SEI, improving the solvation structure of lithium-ion batteries to regulate the interface reactivity, and doping lithium metal in the grain boundary micro-region to improve the electrode surface microstructure and optimize the performance.

The session was hosted by Prof. Bian Hongtao, and attended by Ms Guo Xin’ai from the Center of Large Instruments and graduate students from the Institute, who discussed with Zhang Xueqiang about the electrochemical process and control strategy of electrode/electrolyte interface in secondary batteries.
