    Greenhouse gas emissions and the depletion of finite resources are two major environmental issues brought on by the current reliance on fossil fuels to meet energy demands. Making the switch to renewable energy sources like solar and wind is crucial, but their inconsistent availability calls for efficient storage options. Among these, electrochemical energy storage devices supercapacitors in particular stand out as viable choices because of their long-lasting performance and high power efficiency. As a result, the supercapacitor, an energy storage device, has garnered a lot of attention because of its long lifespan, high cycling stability, environmental safety, and quick charge/discharge rate. In comparison to batteries, supercapacitors have a very high power density. Supercapacitor electrode material is made with higher energy and power density and excellent cyclic stability. In present work, ZIF-8, ZIF-67, MXene, Core shell ZIF-8/ZIF-67 and final composite MXene@ZIF-8/ZIF-67 were synthesized. The final composite was synthesized by self-assembly method with non-covalent interactions. The fabricated material was analyzed by FTIR. Different electrochemical characterizations such as CV, GCD and EIS were performed. The active electrode material was coated on carbon cloth by drop casting method. The potential window is from -0.2 to 1.0 V in 3M sulphuric acid. Composite has specific capacitance 83.3 F/g at 0.5 A/g current density with power and energy density at 0.25 Wkg-1 and 43.3 Whkg-1. This is a good material for enhancing the supercapacitor performance.
