Abstract: Thick cathodes associated with cylindrical lithium-sulfur batteries. The cathodes include one or more structured layers of agglomerates of carbonaceous particles disposed on opposing sides of a cathode current collector. The structured layers on each side of the cathode current collector may be characterized by varying agglomerate size and thickness of the structured layers. The structured layers of agglomerates may improve electrochemical kinetics and sulfur utilization within thick cathodes. The structured layers of agglomerates may decrease the number of interconnection or failure points between agglomerates disposed across the thickness of the structured layers on each side of the cathode current collector and mitigate mechanical stresses during the formation of a cylindrical jelly roll. Lithium-sulfur batteries including thick cathodes.

Abstract: A lithium-sulfur cylindrical cell. The cell includes a cylindrical shell defining an inner volume, and a jelly roll disposed within the inner volume. The jelly roll includes an anode comprising lithium, where the anode is configured as a freestanding assembly. Additionally, the jelly roll comprises a cathode comprising sulfur. Further, the jelly roll comprises a first separator between a first side of the anode and a first side of the cathode. In cylindrical cell formats, the jelly roll comprises a windable second separator. As the jelly roll is wound, the second separator may come in direct contact with both a second side of the anode and with a second side of the cathode. Alternatively, as the jelly roll is wound, the second separator may come in direct contact with the second side of the anode and with a cathode current collector.
