429 66, 429 54, 429120, 429159, 429161, 429175

Mechanically and thermally improved rechargeable batteries and modules. 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. Finally the batteries, modules and packs thereof 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 ambient thermal conditions, so as to maintain the temperature of the rechargeable battery system within the desired operating range thereof under variable ambient conditions.

F28D 1500

16510412, 165DIG 902, 62477, 62480, 62 462, 420900

A hydrogen cooled hydrogen storage unit. The unit employs excess hydrogen flow between hydrogen storage alloy rods in the hydrogen storage unit in order to provide convective cooling thereof. The unit provides for high packing density of the storage materials. The unit also allows for efficient thermal transfer of heat energy from a central source of heat through the rods thereof during discharge of the stored hydrogen. The hydrogen storage rods of the unit are encased in an encapsulant layer which prevents entrainment of the hydrogen storage material in the high flow rate hydrogen.

4292182, 205413, 241 16

An anti-pyrophoric hydrogen storage material having an engineered surface oxide to enhance initial activation and a method for making the same. The method for making. the hydrogen storage material includes the steps of providing a hydrogen storage powder and oxidizing the powder with a controlled oxidation reaction. In a preferred aspect hereof, the method includes providing a bulk hydrogen storage alloy; hydriding the alloy to form a comminuted material; and oxidizing the surface of the comminuted material with a controlled oxidation reaction. In another preferred aspect hereof, a passivating material is added to the comminuted material prior to the step for oxidizing to enhance initial activation. In still another preferred aspect hereof, at least one sacrificial modifier is provided in the particalized material to enhance initial activation.
