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.

Abstract: A secondary battery recombination system includes catalyst and hydrophobic gas diffusion layers defining an electrode that recombines hydrogen and oxygen into water, and a scaffold encapsulating and in non-bonded contact with the electrode. The electrode may be carbon cloth, carbon felt, carbon foam, or carbon paper. The scaffold may be expanded metal or perforated foil.

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.

Abstract: An improved electrolyte including a fire-retardant additive suitable for application in wide temperature cell and/or battery operation with safer cell design, a battery including the electrolyte and a separator optionally containing a fire-retardant additive, improved electrical and thermal conductive electrodes are disclosed. The presence of the fire-retardant additive reduces flammability of the electrolyte and improved the overall safety of the battery.

Abstract: A system and method use an open-circuit voltage (OCV) method of calculating a state-of-health (SOH) of a chemical battery. The OCV system and method includes charging the battery to a maximum charge potential, determining an open-circuit voltage (OCV) of the battery after waiting a predetermined period of time after completion of the charging, and determining the SOH of the battery based on the determined OCV of the battery. Another system and method use a time-to-charge (TTC) method of calculating a state-of-health (SOH) of a chemical battery. The TTC system and method includes monitoring and storing a charge time of the battery in a memory and scaling the stored charge time to form an SOH indication.

Abstract: A battery case houses a battery with a plurality of non-prismatic electrochemical cells and at least one electronic component. The battery case includes a plurality of cell housings and at least one electronic component housing that accommodates the at least one electronic component. The plurality of cell housings each (1) define an internal space sized to accommodate one of the electrochemical cells, and (2) include (a) an internal surface at least a portion of which is shaped to substantially correspond to a non-prismatic exterior surface of the one of the electrochemical cells to be housed by the cell housing, and (b) an external surface at least a portion of which follows contours of a corresponding portion of the inner surface.
