Cosolvent Electrolyte Design for Li–S Batteries: Suppressing the Shuttle Effect via Phase Separation

open access: yesAdvanced Materials, EarlyView.
The impact of introducing cosolvents are investigated with diverse properties into a high‐donor‐number solvent for Li–S batteries. This approach regulates LiPS solubility and S3•− radical formation, strongly influencing sulfur redox kinetics. Moreover, a cosolvent with low miscibility effectively suppressed the shuttle effect, thereby enhancing cycling
