Abstract
A porous interlayer for a lithium-sulfur battery includes an electronic component and a negatively charged or chargeable lithium ion conducting component. The electronic component is selected from a carbon material, a conductive polymeric material, and combinations thereof. In an example, the porous interlayer may be disposed between a sulfur-based positive electrode and a porous polymer separator in a lithium-sulfur battery. In another example, the porous interlayer may be formed on a surface of a porous polymer separator.
