On March 13, 2025, Professor Xie Jia, a renowned scholar from Huazhong University of Science and Technology, accepted the gracious invitation of Professor Tang Yuxin from the College of Petroleum and Chemical Engineering at Fuzhou University to visit our research group for a fruitful academic exchange. In the Youer Lecture Hall, Room 101, South Quangang Building, Professor Xie delivered an enlightening academic presentation titled "Lithium Battery Energy Storage: From Lithium-Ion to Lithium-Metal Batteries" to the attending faculty and students.
In recent years, with the rapid growth in demand for large-scale lithium battery energy storage, the focus has shifted to achieving safe and efficient lithium-ion transport and storage. Professor Xie Jia has addressed this field's critical challenges by concentrating on three core issues: concentration polarization effects, thermal runaway risks, and the challenges of lithium replenishment throughout the battery's lifecycle. Regarding the issue of concentration polarization, Professor Xie innovatively proposed an optimization strategy for low-tortuosity ion transport pathways, validated through experiments with wood-based ultra-thick electrodes, ice-templated low-tortuosity electrodes, and double-layer thick electrodes. To tackle the lifecycle lithium replenishment challenge, he developed a direct coating technology using lithium oxalate, combined with a multi-stage lithium replenishment method activated by differential potentials, and optimized it synergistically with pre-lithiation techniques using metallic lithium, significantly enhancing the battery's cycling performance. In the realm of thermal runaway prevention, Professor Xie designed a novel lithium-repellent solvent system, constructed a two-dimensional solvation structure that is both lithium-philic and lithium-repellent, and elucidated the synergistic mechanism between weak lithium-repellent and strong lithium-philic interactions, successfully achieving precise regulation and decoupling of lithium-ion activity and safety. These research findings provide crucial theoretical support and practical guidance for the further development of lithium battery energy storage technology.
Professor Xie's presentation resonated widely among the faculty and students, igniting their desire for knowledge and passion for exploration. During the interactive session, the atmosphere was vibrant, with faculty and students engaging in deep and productive discussions with Professor Xie on cutting-edge phenomena and challenges in the field of batteries. This exchange not only enhanced mutual understanding but also laid a solid foundation for future academic collaboration and disciplinary advancement.
