Operando transmission X-ray microscopy and in situ X-ray fluorescence microscopy have enabled mapping the evolution of sulfur and related polysulfide intermediates35,36,37. Employing X-ray absorption spectroscopy, Wang et al. quantified the typical chain length of polysulfides upon discharge, presenting the initial estimate of relative price constants for polysulfide transformations38. A thorough...
