Abstract
A lithium-sulfur battery includes a casing having a length and a width, the casing including at least an anode and a cathode wound into a jelly roll oriented parallel to the length of the casing, an electrolyte disposed in the lithium-sulfur battery, a negative terminal extending along the length of the casing, and a positive terminal extending along the length of the casing, the positive terminal and the negative terminal parallel to one another.
Claims8
A lithium-sulfur battery including:
- a lid circumferentially welded to a cylindrical casing;
- a cylindrical jelly roll including:
- an anode including one or more of lithium or lithium-containing alloys;
- and
- a cathode including one or more structured layers of agglomerates of carbonaceous particles disposed on opposing sides of a cathode current collector;
- a negative terminal disposed along the length of the cylindrical casing and attached length-wise to the anode, wherein the negative terminal is partially exposed outside the casing;
- and
- a positive terminal including a mandrel attached to the cathode and separated from the casing by an insulator.
