Robba, A. published the artcileFingerprinting Mean Composition of Lithium Polysulfide Standard Solutions by Applying High-Energy Resolution Fluorescence Detected X-ray Absorption Spectroscopy, Safety of 2,5,8,11,14-Pentaoxapentadecane, the main research area is lithium sulfur battery polysulfide solution x ray absorption spectroscopy.
In a lithium/sulfur (Li/S) battery, the reduction of sulfur during discharge involves a particular mechanism, where the active material successively dissolves into the electrolyte to form lithium polysulfide intermediate species (Li2Sx), with x being a function of the state of charge. In this work, sulfur K-edge resonant inelastic X-ray scattering measurements were performed for the characterization of different Li2Sx polysulfide standard solutions High-energy resolution fluorescence detected X-ray absorption spectroscopy allowed clear separation the pre-edge absorption peak corresponding to terminal sulfur atoms from the main absorption peak due to internal atoms and allowed quant. evaluation of the evolution of the peak area ratio as a function of the polysulfide chain length. Results of this exptl. work demonstrate that the normalized area of the pre-edge is a reliable fingerprint of the Li2Sx mean chain length in agreement with recent theor. predictions. As a perspective, this work confirms that operando HERFD XAS can be used to differentiate mean polysulfide composition, which is key issue in the characterization of Li/S cells.
