Abstract

The transition in the composition, electrical and fracture properties of graphene oxide paper (GO) in at the anode (aGO) and cathode (cGO) of lead /sulphuric acid boundary have been studied. Higher thermal stability and lower weight loss of aGO (34wt % at 800 ˚C) with XRD peak at 2ϴ = 10.5˚ showed the reduction of the ordinary GO paper (95wt % at 800 ˚C). The fractographs from the SEM showed that the cGO failed by ductile rupture of a higher degree than the ordinary GO paper, while that of the aGO was brittle cleavage. UV-Vis, Fourier Transform Infrared and X-ray Photoelectron Spectroscopies showed the changes in functional groups, via the interaction of graphene oxide functional groups with protons, adsorbed oxygen containing ions. Graphene/lead oxide based composite was achieved by covalent interactions. Non-covalent complexation of metal ions with slight reduction gave rise to stronger graphene oxide paper at the cathode. The electrical conductivity of aGO are 1.61 x 106 S/m and those of the cGO are 4.27 X 105 S/m. This foremost work is useful for further study of graphene oxide electrochemical reduction and metallic oxide functionalization for electrode materials in advanced lead-carbon batteries.
