[en] Managing energy demand is essential for ensuring a reliable and sustainable supply, reducing environmental impacts, and achieving energy security. Governments, businesses, and individuals are crucial in shaping energy demand through policy, technology adoption, and behavioral changes. Sustainable energy planning and infrastructure development aim to balance the growing energy demand with environmental and economic goals. Energy storage devices can shave off-peak demand on the grid, reducing the need for expensive and environmentally harmful peaker power plants. This can lead to cost savings and more efficiency. Among various energy storage devices, Supercapacitors play a significant role in energy storage and have particular advantages regarding power delivery, cycle life, and dependability. They are progressively incorporated into diverse technologies and systems to improve energy storage and management solutions across numerous industries. Recently, materials like Transition metal oxides, Conducting Polymers, Carbon-based materials, and Metal-organic frameworks (MOFs) have been utilized for energy storage devices. Among these, ZIF-67 (Zeolitic Imidazolate Framework-67) gained more attention because of its various properties. It is a type of MOF and a promising material due to its high surface area, porous structure, and tunable properties. It is synthesized from relatively abundant and environmentally friendly materials, making it a potentially sustainable choice compared to other supercapacitor materials for energy storage. In the present work, a simple stirring approach is used for the synthesis of ZIF-67, and it is confirmed using X-ray Diffraction (XRD). Morphology is being studied using Scanning electron microscopy (SEM), and the obtained material's electrochemical performance, that is, cyclic voltammetry (CV), Galvanostatic Charge/Discharge (GCD), and Electrochemical Impedance Spectroscopy (EIS) tests, are being investigated on the CHI760E electrochemical workstation (author)
