Executive Summary : | Scientific research communities are focusing on developing sustainable and efficient energy devices to reduce fossil fuel consumption and greenhouse gas emissions. Asymmetric supercapacitors are being considered as a better option than batteries due to their high specific energy supply without compromising specific power. Metal chalcogenides, with their high specific surface area, faradaic nature, and excellent electrical conductivity, meet these criteria. The synthesis of metal chalcogenide is being done via a facile hydrothermal technique, and carbon-based materials like waste bio-derived carbon and graphene derivatives are being synthesized to increase conductivity and stability during long cycles. The goal is to reduce material synthesis and fabrication costs, making these devices highly useful for societal energy needs. |
