The Multivalent Battery Research Group operates within the Department of Advanced Energy Storage Technology at the Qingdao Institute of Bioenergy and Bioprocess Technology (Shandong Energy Institute), Chinese Academy of Sciences. To meet the increasing demand for the storage and utilization of renewable energy in large scale, our group focuses on advancing rechargeable magnesium and calcium batteries, by leveraging the abundance of alkaline-earth metal resources.
Our research aims to elucidate the transport behaviors and storage mechanisms of divalent alkaline-earth metal ions in both solids and solutions, overcoming the thermodynamic and kinetic challenges inherent in multi-electron transfer processes. By developing high-performance cathode materials and electrolytes, we strive to enhance the efficiency and viability of these battery systems.
Beyond multivalent batteries, we extend our insights into multi-electron transfer reactions to other electrochemical storage and conversion systems. For instance, we design high-energy cathode materials for lithium/sodium batteries by activating anionic redox in cathode frameworks. Additionally, we explore sustainable electrochemical ammonia synthesis, utilizing the high reactivity of alkaline-earth metals to develop efficient and environmentally friendly approaches.
Through these efforts, we envision pioneering low-cost, high-performance, and sustainable electrochemical technologies for gird-scale energy storage and other applications, contributing to a cleaner and more efficient energy future.
