Wound electrode assembly for lithium oxyhalide electrochemical cell
A recently granted patent (Publication Number: US11923511B2) discloses an innovative electrochemical cell design comprising a casing and an electrode assembly housed inside. The electrode assembly includes a U-shaped anode with an anode active material, a cathode with a cathode material, a separator to prevent direct contact between the anode and cathode, and a catholyte in association with both electrodes. The unique configuration ensures that the anode, cathode, and separator form a wound-shaped assembly encircling a center point, with specific intersecting points for the anode and cathode reference radii. Additionally, the cell may include a spring for applying a biasing force and features a glass-to-metal seal, stainless-steel components, and specific catholyte compositions.
Furthermore, the patent details variations in the electrode assembly design, including different materials for the anode, cathode, and current collectors, as well as specific molar ratios for salts in the catholyte. The cathode material may include a binder for improved performance, and the anode outer portion is longer than the inner portion. The design also ensures minimal magnetic flux density and specific angles for the distal ends of the electrode components. Overall, the patent highlights a novel electrochemical cell structure with various configurations and components aimed at enhancing performance and efficiency in energy storage applications.
