Kg-Scale Conversion of Coal Based Industrial Waste to a Graphitic Material for Application As an Excellent Anode Material in Lithium-Ion Battery

Abstract

This work aims at kg-scale conversion of typical steel-industrial graphitic waste to an efficient energy storage material. In typical steel industries, coal-based carbon-rich industrial waste is generated in at least several tons per month. This waste is typically landfill waste posing a significant environmental hazard. Therefore, converting it into value-added carbonaceous material is highly beneficial. In this work, graphitic material was prepared from coal-based waste and tested as the anode in a Lithium-ion battery. The converted material's structural, morphological, and compositional details were thoroughly studied. The electrochemical charge-discharge of this graphitic material was tested by using it as an anode material in a Li-ion battery. The results showed that the converted graphitic material is on par with the commercial graphite used as an anode in Li-ion batteries.
