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.

Abstract: A battery 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 configured as a freestanding assembly having first and second sides, a double-sided cathode having a cathode current collector sandwiched between sulfur-containing first and second cathode layers, a first separator between the anode first side and cathode first layer, and a second separator in direct contact with the anode second side and cathode second layer. The double-sided cathode comprises particles each including a first zone of first pores and a second zone of second pores. The battery provides a lithium-sulfur cylindrical cell configuration with a freestanding lithium anode and double-sided sulfur cathode structure.
