On April 28, 2025, Professor Peng Dongliang from Xiamen University、Associate Professor Xia Dingguo fromfrom Ningbo Institute of Materials Science, CAS were invited by Professor Tang Yuxin of the School of Chemical Engineering of the University to give a special academic report.
1.Professor Peng Dongliang give a lecture entitled “Electrode Material Design and Performance Regulation for Next Generation of High Energy Density Li-ion Battery”
High-energy anode and cathode materials are the key to develop the next generation of high-energy lithium batteries. Prof. Peng's team has carried out more in-depth research on high-energy lithium metal anode and lithium-rich manganese-based cathode materials in recent years, and has made some research progress as well as encountered some new challenges. In particular, the team has solved the problems of low first-time Coulombic efficiency, poor multiplicative performance, and serious capacity and voltage degradation of lithium-rich manganese-based cathode materials from different perspectives and strategies, initially established the constitutive relationship between different modification strategies and electrochemical performance, explored an effective scheme to synergistically improve the comprehensive electrochemical performance of lithium-rich manganese-based cathode materials, and developed several kinds of simple, high-efficiency, scaleable We have developed several simple, efficient and scalable key preparation technologies for high-capacity lithium-rich manganese-based cathode materials. The obtained results provide some new ideas for the research and development of new high energy density lithium batteries.
Prof. Peng Dongliang's special report firstly inspired teachers and students with his own experience, and then systematically analyzed the latest breakthroughs in the field of electrochemical energy storage from a forward-looking perspective, which triggered in-depth thinking and enthusiastic discussion among teachers and students. In the interactive session, the participants started professional dialogues on high energy density battery materials, and conducted multi-dimensional academic collisions on the engineering application of solid state electrolyte and other cutting-edge directions.

2.Associate Professor Qiu Bao give a lecture entitled “Sharing of Research Experience on Li-rich Manganese-Based Materials”
Associate Professor Qiu reported that the reaction mechanism and performance advantages of Li-rich manganese-based cathode materials were systematically explained in the academic report. He pointed out that although these materials can achieve ultra-high specific capacity by virtue of their unique anion redox mechanism, they still face significant technical bottlenecks in practical applications: with the increase of cycling times, the materials will experience continuous voltage degradation phenomenon, and this “aging effect” seriously restricts the prospects of their commercialization. To address this key scientific issue, Associate Professor Qiu focuses on how to effectively improve the cycling stability of the materials while maintaining their high energy density characteristics, and proposes innovative solutions from various perspectives, such as material design and interface regulation.
Associate Professor Qiu reported that his presentation not only analyzed the cutting-edge research progress of lithium-rich cathode materials, but also innovatively combined academic exploration with scientific research practice, and systematically shared the key elements and multi-party collaborative mechanism in the process of publishing high-level papers. His unique academic insights triggered a wide range of resonance with the participating teachers and students, and the interactive exchange atmosphere was warm.
