  • Publication number: 20050112471
    Abstract: A nickel-zinc electrochemical cell is disclosed using a polymer matrix separator. The polymer matrix separator includes a polymerization product of one or more monomers selected from the group of water-soluble, ethylenically-unsaturated acids and acid derivatives, and a crosslinking agent, and serves as a primary or supplemental source of electrolyte ionic species for the electrochemistry. Ionic species is contained as a solution phase within the polymer matrix membrane, allowing it to behave as a liquid electrolyte without the disadvantages. In secondary batteries (i.e., rechargeable), polymer matrix membranes are particularly useful as both an electrolyte reservoir and as a dendrite resistant separator between the charging electrode and the zinc electrode. The polymer matrix membrane protects the electrodes from corrosion and prevents zinc oxidation product from the zinc electrode to contaminate the electrolyte.

  • Patent number: 5576118
    Abstract: This invention relates to a hydrogen storage alloy electrode prepared from an active material comprising a magnesium based alloy and a Ni, P based metallic compound. The magnesium based alloy is coated while in powder form with a Ni, P based metallic compound and activated by heat. The hydrogen storage alloy electrode produced from this active material is able to absorb and desorb hydrogen even under normal temperature and pressure. The alkali battery assembled with the electrode prepared from the activated alloy material has high energy density and charge-discharge capacity and can be used in large scale electrical equipment, especially electrically operated vehicles.

  • Patent number: 5358800
    Abstract: This invention relates to a hydrogen storage active material comprising an alloy having the formula MmNi.sub.5-x-y-z Zn.sub.x Q.sub.y R.sub.z, in which Q.dbd.Al, Ca and Sr, R.dbd.Li, Na and K, 0<x.ltoreq.1, 0<y.ltoreq.0.8 and 0<z.ltoreq.1. An alloy phase of zinc is formed between the surface coating and the alloy base after treatment of the alloy powder by surface plating. As a result, the electrochemical capacity as well as the life of the hydrogen storage alloy electrode formed is increased significantly while the cost is greatly reduced by employing Zn.
