Abstract
This study introduces a successful modification of the bipolar electrochemistry (BPE) method to efficiently produce and deposit high-quality reduced graphene oxide onto a conductive substrate. This innovative approach integrates material production and device fabrication into a single-step process that is straightforward, controllable, cost-efficient, and environmentally friendly. Microstructural analysis of the deposited material reveals the formation of oriented graphene sheets on the substrate. For micro-supercapacitor fabrication, interdigitated gold microelectrode arrays are generated through regular photolithography and subsequently employed as the conductive substrate in the BPE process. The electrochemical assessment of the fabricated device through cyclic voltammetry and galvanostatic charge/discharge verifies its outstanding specific areal capacitance. Notably, electrochemical impedance spectroscopy unveils exceptional high-frequency responses, promising potential applications in AC/DC filter systems. A comprehensive presentation of the detailed results will be delivered at the upcoming conference.
