Abstract
<jats:p>The purpose of the work is to develop a method for the synthesis of graphene on a metallic current collector in a hydrocarbon flame under atmospheric conditions. It is known that the layer of graphene on the surface of the metal current collector increases electrical conductivity, chemical resistance to electrolytes used in supercapacitors, and increases the specific capacity of the capacitor due to the double electrical layer of carbon on the basis of graphene. The method of synthesis of graphene in the flame under atmospheric conditions, specifically on the metal surface of the current collector, was proposed and studied for the first time in the work in order to improve its operational and electrochemical characteristics. Considering that flame nanostructures form almost instantly, within 10-5 to 10-3 seconds, the process of flame-induced graphene synthesis on a metal current collector also occurs in a short time, which is a significant advantage compared to the CVD method. It is concluded that flame-induced graphene synthesis is promising for applications that do not require high-quality graphene, particularly for electrodes in electrochemical energy storage devices (supercapacitors, lithium-ion batteries).</jats:p>
