Project Overview
The reduction of fossil fuels and increasing environmental conditions necessitate the development of renewable energy storage systems (ESS) and flexible devices for electronic applications. Metal-ion batteries (MIBs) and electrochemical double-layer capacitors (EDLCs) are the most prominent ESS, but their low power density and energy density limit their applications. Metal-ion capacitors (MICs) are a hybrid of EDLCs and MIBs, offering high power and energy density. To achieve high-capacity capacitors, researchers aim to fabricate morphologically controlled bimetallic metal-organic frameworks (MOFs) to improve metal-ion exchange rate, surface area, and chemical activity. Nanostructures like porous MXene (Ti₃C2Tx) have been studied for their outstanding electric conductivity and surface redox reactions. In-situ spectroscopic measurements and theoretical studies can provide insights into charge carrier density at the electrode surface. The proposal aims to engineer a 3D porous architecture material like titanium carbide-based MXene with optimized bimetallic MOF for anode material in MICs. The solid-state electrolyte will be prepared by adding metal-ion-based ionic electrolytes to a polymer matrix.
