Abstract
In this work, the effect of the synthesis conditions on exfoliated graphite and its properties was investigated. Exfoliated graphite was obtained via thermal reduction of graphite oxide at temperatures of 250–350°C. The influence of the synthesis conditions (temperature and heating rate) on the properties of exfoliated graphite (product yield, bulk density, specific surface area, specific capacitance and others) was determined via direct experimental design method. The ability to use exfoliated graphite in supercapacitors was determined on the basis of the specific capacitance data. The highest specific capacitance of exfoliated graphite was found to be 129 F/g.
