        TITLE
Revealing spatiodynamics of lithium ion battery primary particles via synchrotron-based operando x-ray microscopy


    ABSTRACT
Electrochemistry plays a significant role in energy storage and conversion technologies, such as lithium-ion batteries, fuel cells, and microbial fuel cells. Because of porous and heterogeneous nature of the electrodes in these applications, the conventional current-voltage measurement shows certain limit in untangling complexity of electrochemical reactions (charge transfer, mass transport, chemical reactions and so on). Here in my talk, I will introduce the in-situ electrochemical platform combined with synchrotron-based X-ray spectromicroscopy which visualizes nanoscale charge transfer and electrochemical reactions of individual battery particles. [1,2] Within individual particles, spatial variations in the electrochemical reaction rate control lithium ion insertion pathway. I will also discuss how this technique is expansively applied to other electrochemical systems in my group.
