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. The electrochemical tests have shown that the mockup batteries with newly-developed nickel oxide electrodes based on nickelized carbon/graphite felt have surpassed all requirements of the international standard IEC 62259:2007.
