Model Membrane‐Free Li–S Batteries for Enhanced Performance and Cycle Life

The success of the rechargeable Li–S cell is 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 c...

Descripción
Sumario:The success of the rechargeable Li–S cell is 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(−1) after 100 cycles. [Image: see text]
