оксидноникелевый электрод

A study of the porous structure and discharge characteristics of electrochemically impregnated nickel oxide electrodes based on nickel- ized graphitized felt«Voilocarb-22» is conducted. It is shown that the developed technology of nickel oxide electrodes fabrication that involves such operations as nickel plating of the substrate, electrochemical impregnation, electrode formation and pressing allows forming polydisperse structured electrode active material with pore sizes ranging from 0.01 pm to 100 pm.

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.
