BIFUNCTIONAL SEPARATORS FOR LITHIUM-SULFUR BATTERIES

摘要

The present disclosure relates to a lithium-sulfur rechargeable battery containing a lithium-containing anode, a sulfur-containing cathode, and a bifunctional separator having a microporous, conductive layer facing the cathode of the battery. The bifunctional separator can inhibit polysulfide diffusion and improve sulfur cathode material reutilization to improve cell cycling stability and discharge capacity.
