摘要： Active material for a positive electrode of a rechargeable alkaline electrochemical cell is made with nickel hydroxide particles or cobalt-coated nickel hydroxide particles treated with strongly oxidizing reagents such as alkali metal persulfate in alkaline solution. The active material also may be made with cobalt-coated nickel hydroxide particles having a high percentage of cobalt(III) on a surface or an average cobalt oxidation state of about 3 measured across the particles. The treated nickel hydroxide or cobalt-coated nickel hydroxide decreases the cobalt solubility in the alkaline electrolyte and increases the high-rate charge and discharge capability. The lower cobalt solubility decreases cobalt migration that can increase self discharge and lead to premature failure.
摘要翻译： 可充电碱性电化学电池的正极的活性材料由氢氧化镍颗粒或用强氧化剂如碱金属过硫酸盐在碱性溶液中处理的钴包覆的氢氧化镍颗粒制成。 活性材料也可以由在表面上具有高百分比的钴（III）的钴涂覆的氢氧化镍颗粒或在整个颗粒上测量的约3的平均钴氧化态约3制成。 经处理的氢氧化镍或钴包覆的氢氧化镍降低了在碱性电解液中的钴溶解度，并提高了高速率的充放电能力。 较低的钴溶解度降低了钴迁移，可以增加自放电并导致过早的失效。

摘要： An improved Ni—Zn cell with a negative electrode substrate plated with tin or tin and zinc during manufacturing has a reduced gassing rate. The copper or brass substrate is electrolytic cleaned, activated, electroplated with a matte surface to a defined thickness range, pasted with zinc oxide electrochemically active material, and baked. The defined plating thickness range of 40-80 μIn maximizes formation of an intermetallic compound Cu3Sn that helps to suppress the copper diffusion from under plating layer to the surface and eliminates formation of an intermetallic compound Cu6Sn5 during baking to provide adequate corrosion resistance during battery operation.
摘要翻译： 在制造期间镀有锡或锡和锌的负极基板的改进的Ni-Zn电池具有降低的放气率。 将铜或黄铜衬底电解清洗，活化，用无光泽表面电镀至规定的厚度范围，用氧化锌电化学活性材料粘贴并烘烤。 限定的电镀厚度范围为40-80μIn，使金属间化合物Cu3Sn的形成最大化，有助于抑制铜从电镀层扩散到表面，并消除了在烘烤过程中形成金属间化合物Cu6Sn5，以在电池工作期间提供足够的耐腐蚀性。
