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： The nickel hydroxide particles for a nickel hydroxide electrode may be treated using an alkaline solution of a strong oxidizing agent such as sodium or potassium persulfate to modify the surface nickel hydroxide structure. The resulting modified surface structure has been found to impart various benefits to electrodes formed from the nickel hydroxide. It is believed that the oxidation of cobalt compounds at the surface of the nickel hydroxide particles results in a highly conductive cobalt compound that plays an important role in the high reliability, high stability and high capacity utilization of nickel electrodes as described herein.

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： Active material for a negative electrode of a rechargeable zinc alkaline electrochemical cell is made with zinc metal particles coated with tin and/or lead. The zinc particles may be coated by adding lead and tin salts to a slurry containing zinc particles, a thickening agent and water. The remaining zinc electrode constituents such as zinc oxide (ZnO), bismuth oxide (Bi2O3), a dispersing agent, and a binding agent such as Teflon are then added. The resulting slurry/paste has a stable viscosity and is easy to work with during manufacture of the zinc electrode. Further, the zinc electrode is much less prone to gassing when cobalt is present in the electrolyte. Cells manufactured from electrodes produced in accordance with this invention exhibit much less hydrogen gassing, by as much as 60-80%, than conventional cells. The cycle life and shelf life of the cells is also enhanced, as the zinc conductive matrix remains intact and shelf discharge is reduced.
