Published purpose

High-concentration electrolytes (HCE) show enhanced chemical stability when applied in rechargeable lithium-ion batteries. These electrolytes can also be used as components of liquid-solid hybrid batteries to obtain a combination of improved battery performance and safety. Nevertheless, unwanted decomposition reaction occurring at the interface of HCE and battery electrode potentially hinders the application of HCE in lithium batteries. The goal of this project is to provide a comprehensive understanding of the interfacial reactions that are responsible for deteriorating performances. Our team will use our expertise in molecular spectroscopy and electrochemistry to directly approach the physicochemical properties of the interface from operating batteries. Results obtained from the research will inform the optimal choice of battery materials.
