Abstract: A thin metal film battery cell is formed by one or more plates wound in a spiral thereby forming a roll with two ends at which spiralled edges of the plates are exposed. Each end of the roll is covered by an end strap which includes a body of electrically conductive material from which a tab extends. The body contacts each convolution of the roll while leaving a portion of each convolution exposed so that an electrolyte is able to flow into the roll. The tab attached to and projecting outward from the body for making electical connection to the thin metal film battery cell.

Abstract: The present invention includes a battery case and battery wherein the battery case includes a housing having a top and a bottom and wherein the housing defines a plurality of cavities that are generally octagonal in cross-section. The battery includes a housing defining octagonal shaped cavities, a terminal coupled to the housing, a top and bottom sealingly coupled to the housing, and a plurality of battery cells disposed win the cavities and electrically interconnected in series with the terminal.

Abstract: A metal oxygen-hydrogen battery having sealed cell modules with electrolyte containment and hydrogen venting. The battery includes an outer pressure vessel containing a plurality of cell modules, each having a positive and negative terminal and containing a liquid electrolyte such as potassium hydroxide. Each cell module is enclosed in a flexible sealed bag which is impervious to the flow of the electrolyte. The bag is a multi layer structure preferably composed of thermoplastic film. Each bag is provided with a vent which is permeable to the flow of hydrogen gas but impermeable to the flow of the electrolyte. Electrical leads are connected to the terminals of each cell module and extend in sealed relation through the bag.
