(JP4137368-A)      Ni/H2 battery comprises a Ni anode based on nickel oxide, a cathode made of H2 occlusion alloy which allows occlusion and discharge reaction of H2 electrochemically, an alkali electrolyte and a separator.    The anode, the cathode and the separator contain Zn-cpd.. Pref. anode contains 30-300mg and Zn-cpd. as ZnO and the cathode and the separator contain 0.3-15mg of Zn-cpd. as ZnO.    ADVANTAGE -   The battery has improved recycle life characteristics.    In an example, a MmNi3.55CoO.75MnO.4A10.3 (where Mm = misch metal) alloy ingot was pulverised to 20 microns average size powder, dipped in 7.2 mol KOH zaq.soln. for 1 hr. at 80 deg.C, washed and dried, the powder and ZnO powder were mixed at rate of 99.1:0.1, and filled into foamed Ni, cut to form H2 occlusion alloy cathode, and water repellent fluoro-resin was coated on its surface. A 1400 mAh Ni/H2 battery was fabricated using the cathode, a Ni anode contg. 80mg ZnO and a separator contg. 30 mg ZnO. A 500 cycle life test of the battery showed no lowering of capacity.    (EP477461-B2)      A Ni/H storage battery comprises: a Ni cathode having a nickel oxide as a main active material; anode mainly composed of H-absorbing alloy capable of carrying out the electrochemical hydrogen absorbing andm desorbing reaction; an alkaline electrolyte; a separator.    The Ni cathode' and anode and the separator contain a Zn cpd. Pref. the Zn cpd. contained in the Ni positive electrode is present in the state of a solid . soln., an oxide or a hydroxide in Ni hydroxide. The pref. content of the Zn cpd. e.g. zincate ion, in the Ni positive electrode is 30-500 mg/Ah of battery capacity, and the contents of the Zn cpd. in the negative electrode and the separator are 0.3-1.5 mg/Ah of battery capacity, respectively in terms of ZnO.    Also claimed is a method for mfr. of a Ni-H storage battery.    USE/ADVANTAGE -   Ni-H storage battery has improved reliability,is of simple construction and has improved cycle life characteristics. @(9pp Dwg.No.1/3)@
