heal.abstract	The widespread use of fossil fuels to meet the need for energy in modern society has led to the serious concern of exhaustion of fossil fuels within decades. In addition, burning of fossil fuels to provide energy also results in significant issues of environmental pollution and global warming. All these issues mean it is of high importance to develop alternative energy sources such as by harnessing solar and wind energy that are abundant and clean. Nevertheless, due to the intermittent, non-continuous nature of these renewable energy that depends to intensity of illumination for solar energy and strength of wind, it is essential to store the renewable energy in order to provide reliable power supply. In this regard, finding efficient ways to store renewable energy is equally important to tackle the global issues of shortage of energy and the global warming caused by fossil fuels. Among the various energy storage devices that have been developed, supercapacitors (SCs) have distinct advantages of fast charge/discharge rate, excellent cycle lifetime and high power density. Therefore, SCs have been considered as one of the most important energy stor age systems. Supercapacitors are on a rapid and significant development path, with pos sessing desirable electrochemical benefits, including high power density, long cycle-life, rapid charge–discharge rate, and absolutely demanded commercial features. To understand the real performance of investigated supercapacitors, we considered the electrochemical output of ap plied SC systems. Actually, various types of electrode materials, electrolytes, have been sig nificantly used to improve the electrochemical features in terms of specific capacitance, energy density, power density, and cycle life. Here, we focused on the synthesis of MOFs with different methods and materials, in order to improve the electrochemical performance of the SC, such as the capacitance, the energy density and the cycling stability. Pristine, bimetallic and derived MOF were all tested as single electrode in a three electrode system and they also tested as electrodes in a SC cell. The exper imental set up for the measurements of the SC cell was designed by the software Tinkercad and fabricated in the lab with a 3D printer. Moreover, in this study, hybrid supercapacitor were fabricated using as anode oxides, derived MOF and CNTs. The CNTS were pretreated with different methods. Meanwhile, the cathode was a MOF synthesized in the lab. Additionally, in order to increase the energy density of the SC cell gel electrolyte was used. Finally, a manual for the SCs was created, in order to be used for future projects.	en
