Battery operation: X-ray absorption spectroscopy (XAS) and Li magic-angle spinning nuclear magnetic resonance (NMR) spectroscopy allow the quantitative determination of intermediate species during the discharge and charge processes of Li–S batteries (see figure). NMR can distinguish between soluble and insoluble polysulfides, and XAS confirms the mobility of polysulfides. Both techniques provide information on the mechanisms during battery operation.
