This is a past event.

Dr. Hongmei Luo will present as part of the Department of Chemical Engineering (ChE) Research Series on Thursday (March 16) at 3 p.m. in person in Chem Sci 201 or virtually via Zoom.

Luo will present, "Lithium-Ion Battery Degradation and Cathode-Electrolyte Interface."

Hongmei Luo is a Luke Barry Shires Endowed Professor in the Department of Chemical and Materials Engineering at New Mexico State University (NMSU).  At NMSU, she served as the Associate Dean of Research in the College of Engineering during 2019-2022 and currently she is the College P&T Committee Chair. 


The global energy crisis coupled with the consumption of fossil fuels and the associated environmental issues has stimulated extensive interest in searching for clean and sustainable energy storage and conversion systems. Rechargeable lithium-ion batteries (LIBs) are widely used in mobile devices, hybrid, plug-in hybrid, and electric vehicles. Electrode-electrolyte interface has a strong impact on battery capacity and long-term cycling stability. In order to improve our fundamental understanding of the involved phenomena to accelerate the rational design of cathode materials and stable interface, we will discuss the cathode degradation mechanism and the processes occurring at the cathode-electrolyte interfaces. Using LiMnO4 and Li(Ni,Co,Mn)O2 (NCM) as cathode examples, we will focus on electrochemical characterization, cation mixing, oxygen evolution, thin film deposition, and nanoparticle network synthesis with controlled crystal structures and composition. We will further introduce our work employing the scanning electrochemical microscope to study LIBs degradation in situ and in real-time.
