Lithium–sulfur batteries are a promising electrochemical energy storage technology; however, they are limited by the dissolution of polysulfide intermediates. Now, it has been shown that sparingly solvating electrolytes containing a phase mediator can avoid polysulfide dissolution and accelerate surface-localized solution-phase sulfur reaction to improve battery performances.
