My research project
Two-dimensional (2D) nanomaterials-based composites for flexible Supercapacitor device applicationIn recent years, due to the increased demand for energy, sustainable and renewable energy sources have earned significant research attention. The overconsumption of fossil fuels and severe global warming instructs the scientific community to propose an environmentally friendly alternative. Due to the utmost importance and commercialisation of energy storage systems in consumer electronics, medical science, the automobile industry, defence, and clean energy, we are facing new challenges. Supercapacitors are equipped with the advantages of high energy density (battery) and high-power density (conventional capacitors) among all energy storage technologies. A supercapacitor is an electrical device that stores electrochemical energy in the form of an electric double layer at the electrode/electrolyte interface and pseudocapacitance due to redox reactions. Mechanical folding would be an advantage for thin-film-based flexible supercapacitors. Various studies have examined flexible energy storage/conversion devices with practical applicability in foldable smartphone displays, Google Glass, health care sensors, and computers.
