Thermal treatment of charcoal for synthesis of high-purity carbon materials

Abstract

The use of pure carbon materials in energy storage systems has the enormous potential for improvement of their performance. Among various carbon materials, natural and synthetic graphite is known to be the most widely used for batteries. Nonetheless, biomass as a good auxiliary carbon-containing material can also become a sustainable source of high-purity carbon material for this purpose. To examine these opportunities, a multistage technology comprised by pyrolysis of walnut shells and subsequent thermal purification of carbon residue at 3000 °C has been studied. As a result, high-purity carbon material has been synthesized, it can find the application in energy storage systems, for instance, lithium-ion batteries.
