摘要： An improvement in accumulator batteries having a zinc anode and an oxide cathode (e.g., nickel oxide or silver oxide cathode) is disclosed. The zinc anode and/or separator part between the anode and cathode is vibrated at a frequency and amplitude sufficient to inhibit dendrite growth on the zinc anode. The electrolyte contains excess zinc such that solid zinc oxide is present in the fully charged condition. The separator may be provided with circulation enhancement means. The resulting batteries have long life with a large number of charging and discharging cycles.

摘要： The electrolytic deposition of nickel hydroxide in a porous electrode structure is carried out within the critical temperature range of from about 85* C to the boiling point of the electrolyte, resulting in the formation of high energy density positive electrodes for alkaline nickel cadmium cells. In addition, the electrodes exhibit a high percent utilization of active material and resist flaking or shedding of the active material during formation and cell use.

摘要： Disclosed is a nickel positive electrode for a fiber battery having a long life duration, and also being enabling a high output and high capacity to be attained. For this purpose, the nickel positive electrode for a fiber battery is obtained by coating a carbon fiber with nickel, then causing a cathodic polarization in a nickel nitrate bath using the nickel-coated carbon fiber as a cathode, and then immersing the precipitate, which was deposited on the surface of the carbon fiber by the cathodic polarization, in an aqueous caustic alkali solution.

摘要： An improved zinc anode for use in a high density rechargeable alkaline battery is disclosed. A process for making the zinc electrode comprises electrolytic loading of the zinc active material from a slightly acidic zinc nitrate solution into a substrate of nickel, copper or silver. The substrate comprises a sintered plaque having very fine pores, a high surface area, and 80-85 percent total initial porosity. The residual porosity after zinc loading is approximately 25-30%. The electrode of the present invention exhibits reduced zinc mobility, shape change and distortion, and demonstrates reduced dendrite buildup during cycling of the battery. The disclosed battery is useful for applications requiring high energy density and multiple charge capability.
