Precipitation behavior is crucial to utilizing sulfur cathodes in lithium-sulfur (Li-S) batteries. In this issue of Chem, Rennie and co-workers apply operando scattering techniques to reveal correlations between precipitation reactions and the electrochemical performance of sulfur cathodes and demonstrate that Li⁺ supply in carbon mesopores is significant for precipitation reactions and thus sulfur utilization.
