Abstract

Read online

Lithium sulfur batteries are promising for advanced energy storage, but polysulfide shuttling limits performance lifetime. Here the authors report selenium-doping in a sulfur-based cathode to prevent dissolution of polysulfide intermediates, leading to ether compatibility, high capacity and stable cycling.
