Regulating Solvent‐Separated Ion Pairs to Control Polysulfide Redox for Fast and Stable Room‐Temperature Na‐S Batteries

open access: yesAdvanced Science, EarlyView.
A local high‐concentration electrolyte with tailored solvent‐separated ion pairs is pioneered to design for room‐temperature sodium‐sulfur batteries. This electrolyte allows sparingly dissolved polysulfides and localizes them onto reactive interfaces for liquid‐solid conversion.

In‐Operando FTIR Study to Investigate the Effect of Varying Lithium Salts on Solid Electrolyte Interface (SEI) Evolution in Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
A clear correlation between electrolyte salt chemistry and Solid Electrolyte Interface (SEI) performance in lithium metal batteries is established using in operando FTIR spectroscopy. This study shows that LiTFSI instantaneously forms a robust, inorganic organic hybrid SEI (LiF, Li3N, Li2O, ROCO2Li, ROLi) that minimizes overpotential, while less ...
