On September 1, 2024, Professor He Ping from Nanjing University visited our research group at the invitation of Professor Tang Yuxin from the School of Petroleum and Chemical Engineering, Fuzhou University. He delivered an excellent academic report titled “Electrochemical Reduction of Carbon Dioxide and Lithium-Carbon Dioxide Batteries in Non-Aqueous Systems” in Room 101, Yu’er Building, Quangang Campus.
CO2 electrochemical reduction is one of the mainstream CO2 emission reduction technologies. Conventional CO2 electrochemical reduction reactions based on hydrogen (or protons) can convert CO2 into high-value chemical raw materials such as CO, acids, and alcohols. The novel non-proton lithium-carbon dioxide battery integrates the functions of CO2 fixation and high specific energy supply. It has significant strategic importance for constructing zero-carbon emission energy systems and leading the transformation of carbon-neutral energy technologies. However, the charging and discharging reaction mechanisms of lithium-carbon dioxide batteries are still debated. There are few efficient catalysts that can reversibly catalyze CO2 conversion, and the battery performance often fails to meet practical requirements. To address these issues, Professor He’s team conducted a detailed study on the electrochemical reduction and deposition processes of CO2 in lithium-carbon dioxide battery systems; designed and constructed efficient Ru catalysts to enhance battery reversibility; introduced inorganic molten salts as a new type of electrolyte, significantly improving the energy efficiency and cycle life of the batteries; and regulated CO2 reduction reaction pathways and products using soluble redox mediators based on copper complexes, thus enhancing the battery’s output voltage and efficiency.
In his report, Professor He Ping introduced the reaction pathways of lithium-carbon dioxide batteries, the mechanisms of catalyst action, reaction mechanism regulation, and related in-situ characterization techniques. This aroused great interest among the attending faculty and students and sparked their curiosity. The participants actively engaged in discussions and had in-depth exchanges with Professor Tang Yuxin on related research fields. This exchange not only deepened mutual understanding but also further promoted academic collaboration and the development of the discipline.

This exchange activity provided a valuable academic platform for the faculty and students of Fuzhou University. Through the sharing and discussion of academic reports, it facilitated interdisciplinary collaboration, promoted the sharing and innovation of research results. We believe that such exchanges and collaborations will further advance the development of the electrochemical energy storage field and lay a solid foundation for future research breakthroughs. We look forward to more academic exchange activities to promote close cooperation between the academic and industrial sectors and jointly advance scientific and technological progress and social development.
