Hybrid Materials Based on Carbon Fabric Modified with Transition Metal Oxides and the Possibility of Their Use as Electrode Materials for Supercapacitors

The features of the formation of hybrid electrode materials based on carbon fabric modified with oxides of molybdenum, cobalt, nickel, iron, and tungsten upon polarization by an alternating asymmetric current are studied. It is shown that the fabricated hybrid materials are multiphase systems, the morphology of their surface is characterized by a fragmentary structure. A study of the electrochemical behavior of the produced hybrid materials was condicted during their cycling in an alkaline electrolyte. The calculated specific capacity were 472, 1018, 1496, 1990 mF cm(-2) at current densities of 30, 12, 6, 3 mA cm(-2), respectively. The resulting hybrid electrode materials retain their specific capacity up to 77% after 1000 charge/discharge cycles, which suggests the possibility of their use in symmetrical supercapacitors with an alkaline electrolyte.
