As one of the energy storage systems, supercapacitors have quite long charge-discharge cycle life. Among many kinds of electrode materials, metal organic frameworks (MOFs) have unique properties such as high specific surface areas and large pore volume as supercapacitor electrode materials. Nickel-MOFs consist of binary ligand such as 1,3,5-Trimesic acid (H3BTC) and terephthalic acid (TPA) were used as working electrode materials in three electrode cell for capacitor system. When synthesizing MOFs, it is possible to prepare uniform crystals using hydrothermal synthesis. The morphology of composites was analyzed by field emission scanning electron microscopy (FE-SEM). Electrochemical properties were measured by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) in 6M KOH electrolyte.

AbstractBenzendicarboxylic acid (BDC)-based metal–organic frameworks (MOFs) have been widely utilized in various applications, including supercapacitor electrode materials. Manganese and copper have solid diamond frames formed with BDC linkers among transition metals chosen for MOF formation. They have shown the possibility to enlarge capacitance at different combinations of MOFs and polyaniline (PANI). Herein, reduced graphene oxide (rGO) was used as the matrix to fabricate electrochemical double-layer SCs. PANI and Mn/Cu-MOF's effect on the properties of electrode materials was investigated through electrochemical analysis. As a result, the highest specific capacitance of about 276 F/g at a current density of 0.5 A/g was obtained for rGO/Cu-MOF@PANI composite.

Two types of supercapacitor electrode materials have been synthesized: AC/PANI, activated carbon composites polyaniline by in-situ polymerization of aniline on the surface of activated carbon, and Ni-AC/PANI, the AC/PANI composite dopes with nickel. The microstructure of composites has been examined by scanning electron microscope (SEM). Fourier transform infrared spectroscopy (FI-IR) has been used to determine the molecular structure and chemical bond of the composites. The nickel content has been measured by atomic absorption spectrometry (AAS). The electrochemical performance of the composite has been characterized by cyclic voltammery and galvanostatic charge-discharge in 6mol•L-1 KOH solution using Hg/HgO as reference electrode. Due to the doping of nickel salt, Ni-AC/PANI shows desired microstructure, good high-current charge-discharge performance and good electrochemical behavior with an capacitance of 535F•g-1, 38.2% higher than that of AC/PANI.
