  • Publication number: 20220140419
    Abstract: An aqueous battery system includes an electrode assembly, a recombination device, and a controller. The recombination device has a catalyst that combines hydrogen and oxygen produced by the electrode assembly to form water and generate heat via exothermic reaction. The controller, responsive to a detected temperature or change in temperature associated with the recombination device due to the heat, changes power supplied to the electrode assembly.

  • Patent number: 11128002
    Abstract: Monobloc batteries include compartments containing cells. Terminals extend into the compartments and are electrically connected with the cells via tabs. The tabs are folded to form bent stacks and include openings in partial registration with each other. The terminals extend through the openings and are secured to the tabs. The terminals are off-center relative to the compartments to preserve space for the bent stacks.

  • Publication number: 20210273234
    Abstract: An electrode includes a current collector, a metal shell in direct contact with and encapsulating the current collector, green dendritic columnar growths extending out of the metal shell and having protrusions thereon, and active material in contact with the metal shell and having embedded therein the green dendritic columnar growths. The protrusions penetrate the active material to form a mechanical retainer that prevents delamination of the active material from the metal shell and define localized regions of increased current density during operation of the electrode that promote deposition of the active material first on the protrusions and then on areas of the green dendritic columnar growths adjacent to the protrusions such that the active material electrochemically adheres to the green dendritic columnar growths and the protrusions enlarge during repeated charge and discharge cycling of the electrode.
