C112 OHR (Oliver H. Raymond Civil Engineering Building) Solid Electrolyte Materials for All-Solid-State Batteries

Safety and low energy density are two of the biggest challenges for conventional lithium-ion batteries containing liquid organic electrolytes. All-solid-state batteries, replacing the liquid electrolyte by its solid-state counterpart, are considered as a promising candidate for the next- generation batteries with high energy density and intrinsic safety. As a critical component, solid electrolyte plays a fundamental role affecting battery performance. The ideal solid electrolyte should have excellent ionic conductivity, good thermal stability, high compatibility and electrochemical stability with metallic anode and cathode materials. Promising solid electrolyte materials include perovskites, garnet oxides, and compounds of the NASICON and LISICON families, thio-phosphate sulfides, anti-pevroskites, and complex metal hydrides. This presentation will introduce three types of solid electrolytes: thio-phosphate sulfide (Li3PS4), anti-pevroskite (Li2OHCl), and metal hydride (LiBH4-LiI). Their synthesis, crystal structure, microstructure, morphology, electrochemical stability, and coating technology will be discussed. Sodium (Na)-ion solid conductors, such as Na3SbS4 for rechargeable sodium batteries, will also be presented.

Dr. Hui Wang joined the University of Louisville as an assistant professor in the Department of Mechanical Engineering in the fall of 2016. She is also affiliated with the Conn Center for Renewable Energy Research at University of Louisville. Dr. Wang obtained her PhD degree in Materials Science and Engineering from the Michigan Tech University in 2013 and her thesis research focused on the synthesis of graphene and its applications. She then moved to the Oak Ridge National Laboratory, where she started the research on solid electrolytes and all-solid-state batteries. Dr. Wang’s current research focusses mainly on advanced solid-state materials for electrochemical energy storage devices such as batteries.
