Most of the graphene-based supercapacitor electrode studies in the literature follows the oxidation and reduction synthetic pathway. In this process, graphene oxide (GO) is prepared from natural graphite followed by reduction approaches, for the removal of decorated oxygen-containing functional groups, and to produce reduced graphene oxide (rGO) electrodes. The electrical conductivity of graphene is highly suppressed by the structural defects, and residue oxygen containing functional groups, thereby leaving the self-assembled graphene supercapacitors with a compromised power density and rate capability. Both low surface area and low conductivity of multi-layered graphene weakens the ion adsorption, and charge transportation, thereby affects the resultant capacitance. Consequently, the capacitance of graphene electrode falls in the range less than 300 F g -1 , a much lower value than the threshold theoretical capacitance of pristine monolayered-graphene. In the realm of large-scale pristine graphene production, the inevitability of multilayered structures and defects in the fabrication of graphene electrodes are inevitable, and widely considered difficult. The capacitance performance of mass-produced monolayer pristine graphene falls in the range of theoretical threshold (550 F g -1 ). This creates a space for new methods to improve the performance of graphene-based supercapacitor electrodes .
