It is experimentally established that the use of Ni-Zn batteries as positive oxide-Ni electrodes of metal-cell electrodes on porous polymer bases leads to a significant decrease in their capacity. Reduce zincate poisoning of positive electrodes of this type is possible with the introduction of cobalt hydroxide into the active substance. Various methods of introducing an activating additive into the active mass of the electrode have been studied. It is shown that the chemical deposition of cobalt hydroxide in the pores of the metal-oxide Ni electrode and galvanic deposition of Ni-Co alloy on the surface of Ni-plated fibers of polypropylene base leads to approximately the same increase in the capacity of metal-oxide Nickel electrodes in Ni-Zn batteries.
