Abstract

High conductivity and high level of electrolyte availability are the main requirements of active materials used in Supercapacitors (SCs) to achieve high electrochemical efficiency. In recent years, Metal-organic frameworks (MOFs) have been used as electrode materials for SCs due to their suitability of porosity and high surface area. However, using single-component MOFs in Supercapacitors results in poor electrical conductivity, insufficient stability, and poor mechanical properties, and neutralize the effect of high capacity and efficient performance. In this paper, using a hydrothermal synthesis method, Cu-based MOFs were fabricated and Graphene was added during synthesis to enhance the conductivity of these materials. To investigate the structure of Nanocomposites were used XRD, FTIR, and FESEM analyze. To investigate the electrochemical behavior of electrodes, cyclic voltammetry, electrochemical impedance and repeatability behavior were performed. The Cu based MOFs had a capacity of 372 F. g-1, while its composite capacity with Graphene is 570 F. g-1. In these composites, Graphene enhances electrical conductivity, porosity accessibility, and charge storage through a non-Faradic mechanism and Metal-organic frameworks increase the total capacity with high porosity, porosity adjustable, and charge storage through the Faradic Mechanism.
