Synthesis of Exfoliated Graphite and Study of Its Electrical Conductivity in the Composition of Active Masses of Three-Dimensional Electrodes for Supercapacitors
摘要
Abstract
Exfoliated graphite was synthesized from oxidized thermally expanding graphite under the influence of electromagnetic radiation. The surface morphology was studied using the scanning electron microscopy and the layered structure of the exfoliated graphite was shown. The study of the elemental composition obtained by the method of energy-dispersive X-ray spectroscopy revealed the absence of impurities in the exfoliated graphite. Three-dimensional electrodes were obtained and conductivity of various mixtures of active materials for chemical current sources with synthesized exfoliated graphite was studied.
