Abstract:
Disclosed herein is a multifunctional battery for supplying power to an electrical circuit, and the related method of making the same. Use of the multifunctional battery permits structural integrity and versatility, while maximizing power output of the cells and minimizing the overall weight of the structure. The multifunctional battery includes an open cell interconnected structure comprised of a plurality of open cells so as to provide a structural electrode. The structural electrode is configured to be a load bearing member. The battery also includes interstitial electrodes that are counter electrodes to the structural electrode. The interstitial electrodes are at least partially received within a predetermined number of the cells of the interconnected structure. Additionally, a separator portion is disposed between the structural electrode and interstitial electrodes to serve as an electrical insulator.

Abstract:
The invention described concerns an anode electrode comprising a hydrogen storage material/alloy and a high energy density metal. In addition a hydrogen electrocatalyst may be added to increase the hydrogen reaction rate. The high energy density metal is selected from a group consisting of Al, Zn, Mg and Fe, or from a combination of these metals. A method of production of an electrode comprising a hydrogen storage alloy and a high energy density metal is also described. The method comprises sintering or binding a high energy density metal powder and/or hydrogen storage alloy into at least one thin street, and calendaring or pressing said sheet forming the electrode. The anode electrode may be used in metal hydride batteries and metal air fuel cells.
Abstract:
A method for readily fabricating a negative electrode for a secondary cell. The negative electrode has reciprocal characteristics including the initial activity, high−rate discharge characteristics, and corrosion resistance in good balance and is excellent in recycling. The method comprises a step of mixing negative electrode materials including a conductive material and at least two kinds of AB 5 hydrogen absorbing alloys composed of substantially a single phase, having the same composition, a crystal mean length of 30 to 350 μm, and different ratios (D1/D2) of the crystal mean length (D1) to the crystal mean breadth (D2) and of molding the materials.
Abstract:
An electrode made by applying a paste containing a hydrogen storage alloy, a binder, and a carbonaceous material to a conductive core and then sintering the core in a vacuum or non-oxidizing gas atmosphere. The carbonaceous material acts as a reducing agent to suppress the oxidization of the hydrogen storage alloy at the time of sintering, and so the electrode has a high oxygen gas absorbing power at the time of overcharging. The inner pressure of a battery using such a sintered hydrogen storage alloy electrode as a negative pole hardly increases and the reliability of the battery is high.
