Abstract

Zinc-carbon batteries are consumed daily worldwide. Large amounts of batteries are mainly disposed of improperly due to their low cost and short life cycle. It contains a graphite rod as a positive electrode. Considering that graphite natural resources are not abundant worldwide and that powder and rod graphite are already being used for graphene synthesis, the use of graphite from these discarded batteries is a cheap, sustainable, and nonhazardous process for the synthesis of reduced graphene oxide (rGO). Graphite rod has been removed, pretreated by using acid treatment and sonication to eliminate contaminants, and used as raw material for synthesis of graphene oxide (GO) by electrochemical exfoliation in aqueous electrolytic solution. GO was reduced to rGO using a mild condition and L-ascorbic acid (natural reducing agent) to remove oxygen functionalities and to restore the π-network of the GO. This method does not use reducing agents that are corrosive, combustible, and harmful to human health and environment. The yield of rGO using waste battery graphite was 80%. To optimize the electrochemical exfoliation process, three different voltages were applied (5.0, 7.5, and 10.0 V).

Characterization of the structure and morphology of rGO was examined by scanning electron microscopy (SEM); Brunauer, Emmett, and Teller equation (BET) area; X-ray diffraction (XRD); Raman spectroscopy; dispersive X-ray spectrometry (EDS); and transmission electron microscopy (TEM). rGO has been successfully synthetized. This route can be considered as green, cost-effective, sustainable, and eco-friendly. The 7.5 V is the optimum voltage to produce high-quality graphene.
