Abstract

Abstract : To increase the sulfur content/loading, trap the soluble Li2 S x intermediates, and improve the cycling stability of Li/S batteries, 3D‐interlaced, nitrogen‐doped, micro/mesoporous carbon‐fiber free standing membranes are developed. Extendable multilayers' stacking of the carbon fibers not only allows a greater sulfur content/loading on the cathode, but also helps to better mitigate the diffusion of polysulfide.
