title: Model Membrane-Free Li-S Batteries for Enhanced Performance and Cycle Life.
abstract: The success of the rechargeable Li-S cellis limited in part by the dissolution of lithium-polysulfide in the electrolyte. Remarkably, it is found that removal of the conventional membrane separator in a Li-S cell improves sulfur utilization and cycling performance, whether the sulfur is initially contained in the cathode or electrolyte. An optimized cell design yields discharge capacities as high as 980 mA h g-1after 100 cycles.
