Title:
Synchrotron radiation X-ray probe electrochemical energy storage and conversion
Abstract:
To better understand the real process and mechanism in electrochemical energy storage and conversion is high desirable and critical. However, for most of nanoscale functional materials, drastic structural changes during electro-cycles can lead to the formation of new active sites or different phases, implying complex and distinctive processes. Based on synchrotron radiation X-ray light source, many state-of-the-art X-ray methods can be developed to probe such dynamitic changes in electrochemical processes. Herein, I will present some of our recent studies on the development of multiple/operando X-ray techniques for probing electrochemical catalysts and ion-batteries. The outlook of advanced X-ray techniques will be also discussed with new generation light source.
