METHOD OF PRODUCING HYBRID ELECTRODE MATERIAL BASED ON CARBON FABRIC WITH POLYMER-OXIDE LAYER Russian patent published in 2024 - IPC H01M4/52 C25D5/18 C25D3/02 H01G11/32 

FIELD: electricity; chemistry.

SUBSTANCE: invention can be used in production of flexible electrode materials based on metal oxides and polymer on carbon fabric surface, used in chemical current sources, such as supercapacitors and accumulators. To obtain a flexible electrode material, a layer of tungsten oxides is pre-applied on the surface of the working electrode from carbon fabric, and then co-precipitating oxides of molybdenum, cobalt, iron, nickel from electrolyte, containing ammonium heptamolybdate, cobalt sulphate, iron sulphate, nickel sulphate, cobalt chloride, boric acid, citric acid and polyacrylic acid. Process is carried out at temperature of 60 °C and an electrolysis time of 40 minutes. Carbon fabric is polarized by alternating asymmetric current of industrial frequency of 50 Hz at pH 4.0. Ratio of average densities of cathode and anode currents is 1.5:1 on both sides. Counter electrodes used are stainless steel.

EFFECT: invention improves properties of flexible materials by increasing specific capacity, uniform distribution of oxide compounds in depth of carbon fabric, reducing temperature and duration of electrolysis.
