Abstract

A novel in situ X-ray fluorescence microscopy combined with X-ray absorption spectroscopy technique is reported to investigate the Li-S batteries during electrochemical cycling. The evolution of morphology changes of the electrode is monitored in real time using the X-ray fluorescence images, while the changes of the sulfur chemical state are characterized simultaneously using the X-ray absorption spectroscopy spectra.
