Low‐Cost Higher Loading of a Sulfur Cathode

To increase the sulfur content/loading, trap the soluble Li2Sx 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.
