Executive Summary : | Supercapacitors are an attractive energy storage technology that rely on electrode materials with higher specific surface areas and appropriate micropore structures. Graphene has been explored as an electrode material for supercapacitors, but current techniques are time-consuming and costly. The proposed project aims to fabricate graphene-based electrodes with desired mesoporosity using the shroud plasma spraying technique. This fabrication process is industrial friendly, reliable, and cost-effective, and is expected to overcome defects in conventional graphene-based electrode production techniques. The project will involve spray drying of hybrid graphene nanoplatelates and carbon nanotube, resulting in three compositions of powders. The plasma spraying process will be carried out using an atmospheric plasma spray system, with a shroud attached to protect the plasma jet. The project will also involve characterization of the developed electrode for supercapacitors using the fabricated electrode with optimal properties. The project will be aimed at achieving the desired performance of supercapacitors in terms of processing, capacitance, and scalability. |
