    Abstract: Mechanically and thermally improved rechargeable batteries, modules and fluid-cooled battery pack systems. The battery is prismatic in shape with an optimized thickness to width to height aspect ratio which provides the battery with balanced optimal properties when compared with prismatic batteries lacking this optimized aspect ratio. The optimized thickness, width and height allow for maximum capacity and power output, while eliminating deleterious side affects. The battery case design allows for unidirectional expansion which is readily compensated for by applying external mechanical compression counter to that direction. In the module, the batteries are bound within a module bundling/compression means under external mechanical compression which is optimized to balance outward pressure due to expansion and provide additional inward compression to reduce the distance between the positive and negative electrodes, thereby increasing overall battery power. The fluid-cooled battery pack includes; 1) a battery-pack case having coolant inlet and outlet; 2) battery modules within the case such that the battery module is spaced from the case walls and from other battery modules to form coolant flow channels along at least one surface of the bundled batteries; and 3) at least one coolant transport means. The width of the coolant flow channels allows for maximum heat transfer. Finally the batteries, modules and packs can also include means for providing variable thermal insulation to at least that portion of the rechargeable battery system which is most directly exposed to said ambient thermal condition, so as to maintain the temperature of the rechargeable battery system within the desired operating range thereof under variable ambient conditions.

    Abstract: A metal alloy for use in a wire included in an electrochemical cell is disclosed having an amorphous structure, microcrystalline grains, or grains that are sized less than about one micron. In various embodiments, the microcrystalline grains are not generally longitudinally oriented, are variably oriented, or are randomly oriented. In some embodiments, the microcrystalline grains lack uniform grain size or are variably sized. In some embodiments, the microcrystalline grains have an average grain size of less than or equal to 5 microns. In some embodiments, the metal alloy lacks long-range crystalline order among the microcrystalline grains. In some embodiments, the wire is used in a substrate used in the electrochemical cell. In some embodiments, the metal alloy is formed using a co-extrusion process comprising warming up the metallic alloy and applying pressure and simultaneously passing a core material through a die to obtain a composite structure.
