A sulfur-carbon material, in one example the sulfur-carbon material forms at least part of a cathode in a battery, such as a lithium-sulfur battery. Also, a method of producing the sulfur-carbon material, including a two stage process of adsorbing sulfur into a porous carbon material, and then selectively or preferentially extracting sulfur from the porous carbon material, based on pore size, thereby leaving sulfur remaining in micropores of the porous carbon material. |
