Don’t miss the first of four monthly webinars in our Advanced Characterization Methods for Battery Innovations Webinar Series, where experts will discuss how you can adopt advanced characterization methods that will help you understand battery materials and interphases in your quest for better batteries.

In this first webinar Dr. Y. Shirley Meng, Professor, University of California San Diego (UCSD), will discuss how advanced characterization methods, such as cryogenic electron microscope techniques (cryo-TEM/cryo-FIB) and plasma FIB-SEM, facilitate the understanding of battery materials (thick cathode, Li metal, solid state electrolyte) and interphases for better batteries.

Abstract:
Lithium (Li) metal has been considered as an ideal anode for high-energy rechargeable Li batteries while Li nucleation and growth at the nano scale remains mysterious as to achieving reversible stripping and deposition. A few decades of research have been dedicated to this topic and we have seen breakthroughs in novel electrolytes in the last few years, where the efficiency of lithium deposition is exceeding 99.5%. Here, cryogenic-transmission electron microscopy (Cryo-TEM/Cryo-FIB) was used to reveal the evolving nanostructure of Li deposits at various transient states in the nucleation and growth process, in which a disorder-order phase transition was observed as a function of current density and deposition time. More importantly, the complementary techniques such as titration gas chromatography (TGC) reveals the important insights about the phase fraction of solid electrolyte interphases (SEI) and electrochemical deposited Li (EDLi). While cryo-EM has made significant contributions to enabling lithium metal anodes for batteries, its applications in the area of solid state electrolytes, thick sulfur cathodes are still in its infancy.

In this webinar Dr Meng will discuss a few new perspectives about how future new imaging and spectroscopic techniques such as plasma FIB SEM (PFIB) can accelerate the innovation of novel energy storage materials and architectures.
