Abstract

Influence of cathode and anode polarization of carbon fibrous materials (CFM) in solutions containing alkali metals compounds (LiOH, KOH, Li₂SO₄) is investigated. It is found that steady electrode potential and conductivity change depending on the mode of electrolysis (type of polarization, current density). It is explained by changing of the fibres surface properties. The possibility of creation nonisoelectroconductive electrodes by electrode treatment in the sulfate lithium solution is shown.
