Executive Summary : | Conventional energy sources are insufficient for the current population and rapid technological development, and have negative environmental impacts. Supercapacitors are a promising alternative to batteries due to their superior power density, fast charge discharge rate, and better longevity. The choice of electrode material is crucial, and two-dimensional (2D) layered materials like graphene transition metal dichalcogenides (TMDs), black phosphorus (BP), MXenes, and metal nitrides (MNs) have gained attention for their high surface area, good thermal, chemical, and mechanical stability. However, conventional energy storage devices are not suitable for next-generation compact, portable, and flexible electronics. The main objective of the proposed project is to develop 2D layer-based composite materials for hybrid flexible supercapacitors, aiming to achieve high-performance, reliable, cost-effective, environment-friendly, and shape-conformable electrode materials. Flexible supercapacitors will be the future energy storage devices for smart, flexible, and lightweight electronic devices. Despite progress, there are still many challenges to be addressed in this field. Flexible energy storage devices are still in the preliminary stage of development, and a wide range of electrode materials have been investigated to increase energy density but are limited by poor cyclic stability. The project aims to study graphene/graphene-oxide (GO)/reduced graphene oxide (rGO)/TMDs/MXenes and their hybrid structures for flexible electronics applications. The project will optimize growth conditions, tune the composition of composites, and test the electrochemical performance of the fabricated electrodes. |
