International Business Machines had seven patents in batteries during Q4 2023. IBM has developed an enhanced metal-sulfur battery that addresses the redox shuttle issue seen in traditional batteries of this type. By exposing the battery to an oxidizing gas before or during operation, stability is improved without sacrificing capacity. The battery features a sulfur or hybrid metal halide-sulfur cathode within an electrically conductive material, offering both high capacity and stability.

Application: Oxygen and metal halide and/or halogen enhanced metal-sulfur battery cathodes (Patent ID: US20230369646A1)
The patent by IBM describes an enhanced metal-sulfur battery that addresses the redox shuttle issue seen in traditional metal-sulfur batteries by exposing the battery to an oxidizing gas before and/or during operation. The enhanced battery incorporates a sulfur cathode or a hybrid metal halide-sulfur cathode into an electrically conductive material, providing both high capacity and stability, unlike traditional metal-sulfur batteries.
The claims detail the components and configurations of the enhanced metal-sulfur battery, including the incorporation of an oxidizing gas, specific materials for the anode and cathode, the use of a carbon-based electrically conductive material, and the presence of molecular oxygen in the electrolyte. The claims also cover variations in the cathode composition, the selection of the oxidizing gas, and the specific volume percentage of molecular oxygen in the gas mixture. Overall, the patent aims to improve the performance and stability of metal-sulfur batteries through innovative design and materials selection.
