The global energy crisis, mainly due to the depletion of non-renewable energy resources, demands focused research on advanced energy materials for power generation and green energy storage. Supercapacitors are promising energy storage devices compared with traditional batteries; with elevated power density, high charge-discharge rates, improved cyclic stability and safer operation. However, the usage of supercapacitors is limited due to the relatively lower energy density. A device that could provide high energy and power density simultaneously can be utilized in multi-dimensional applications, such as portable electronics, electric vehicles etc. Therefore, the prime interest in this Ph.D. thesis is to enhance the energy density of supercapacitors, without affecting the power density and cyclic stability. To address this issue, two major strategies have been employed: i) synthesis and utilization of novel green nanomaterials and advanced engineered nanocomposites for high-performance stable supercapacitor electrode, ii) exploration of various combination of electrolytes to enhance the effective potential window of the device. To achieve the goal, different carbon-based nanomaterials, nanostructures, metal oxide nanoparticles and model bio-membranes, along with several aqueous, non-aqueous and polymer-based electrolytes have been utilized to design high performance supercapacitors. In-depth structural and electrochemical investigation have been carried out to understand the electrode-electrode and the electrode-electrolyte interactions and charge storage mechanism. Finally, fabrication and performance analysis of a lightweight, flexible, all-solid-state micro-supercapacitor is presented.
