摘要：

It is shown that the dissolution of elemental sulfur into, and its diffusion through, the electrolyte allows cycling of lithium-sulfur batteries in which the sulfur is initially far removed and electrically insulated from the current collector. These findings help to understand why liquid electrolyte lithium-sulfur batteries can be efficiently cycled, despite the extremely insulating properties of sulfur.
