On April 26, 2025, Prof. Yang Yong from Xiamen University was invited by Prof. Tang Yuxin from the School of Chemical Engineering of Fuzhou University to visit the group for academic exchange and guidance. Prof. Yang Yong listened to Prof. Tang Yuxin's report on the progress of the project, had an in-depth discussion on the research direction of polymer solid-state batteries with the teachers of the group, and gave valuable suggestions on the team's research on the development of new battery systems. In addition, Prof. Yang Yong made a special academic report entitled “Research on Accelerated Aging Analysis and Life Prediction Technology for Energy Storage Batteries” at the Energy Materials Conference in Fuzhou, and members of Tang Yuxin's group participated in the study and exchange.
In the report, Prof. Yang Yong elaborated the aging mechanism of energy storage batteries under different usage conditions, including the structural changes of electrode materials, the decomposition of electrolyte, and the chemical reactions inside the battery. These aging factors not only affect the performance of the battery, but also directly relate to the service life and safety of the battery. In order to study the accelerated aging of energy storage batteries in depth, Prof. Yang's team has adopted a variety of advanced analytical techniques. By means of electrochemical impedance spectroscopy and scanning electron microscopy, they have carefully observed and analyzed the changes in the microstructure and electrochemical properties of the battery during the aging process. Based on these findings, the team established a set of effective life prediction models, which are capable of accurately predicting the remaining service life of a battery based on its initial state and usage conditions.
Prof. Yang Yong's presentation systematically analyzed the latest breakthroughs in the field of electrochemical energy storage from a forward-looking perspective, and his innovative viewpoints triggered in-depth thinking and enthusiastic discussions among the participants. In the interactive exchange session, the participants started professional dialogues around the core topics of accelerated aging analysis, life prediction technology and battery performance improvement of energy storage batteries, and conducted multi-dimensional academic collisions on the engineering application of solid-state electrolytes and other cutting-edge directions.
