FIELD: electricity; nanostructures.
SUBSTANCE: invention relates to materials for electrodes of electrochemical energy storage systems, in particular, vanadium flow-through batteries. Technical result is achieved due to the fact that the precursor for the growth of nanofibres on the surface of the carbon felt is a propane/butane gas mixture at temperature of 750 °C and nickel nanoparticles deposited on the surface of the carbon felt by electrochemical deposition. Functionalisation of the surface of the final electrode with nanofibre content from 2 to 15 wt.% is carried out by calcination in air, which simplifies the manufacturing technology.
EFFECT: increased efficiency of accumulator battery operation.
