Our test results of nickel-cadmium FKM mock-up batteries with metal-felt nickel-oxide electrodes are presented. The discharge characteristics of the tested mock-up batteries with nickel-oxide electrodes made on the carbon-graphite felt basis are shown to exceed virtually all relevant requirements of Russian Railway Industry Standards. The high cyclability of these batteries was established: reduction of the discharge capacity lower than the nominal value was observed after 3100 cycles.

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.
