Abstract
A lithium-sulfur battery includes a casing, a top lid circumferentially welded to the casing, a negative contact surface positioned opposite the top lid, a positive terminal disposed within the casing, welded to the top lid, and configured as a mandrel, a glass insulator circumferentially wound around the mandrel, and a jelly roll including at least an anode and a cathode wound around the mandrel. The jelly roll may also include a top surface not in contact with the top lid, a bottom surface partially in contact with the negative contact surface, and partially in contact with a plurality of non-hollow carbonaceous spherical particles disposed between the bottom surface of the jelly roll and the negative contact surface. At least some of the non-hollow carbonaceous spherical particles may provide one or more electrically-conductive pathways between the bottom surface and the negative contact surface.
