Probing sulphur clusters in a microfluidic electrochemical cell with synchrotron-based photoionization mass spectrometry


We present synchrotron-based mass spectrometry to probe products formed in a lithium sulphide electrolyte. In operando analysis was carried out at two different potentials in a vacuum compatible microfluidic electrochemical cell. Mass spectral observations show that the charged electrolyte formed sulphur clusters under dynamic conditions, demonstrating electrolyte electron shuttling.
