This thesis investigates the synthesis and characterization of nickel/graphene oxide/cobalt(II) (Ni₃C/GO/Co²⁺) and nickel/pyridinium (Ni3C/Pyr) maxenic nanocomposites as efficient materials in supercapacitor. In this research, nickel metal was used to synthesize the 2D maxenic substrate, which was then combined with graphene oxide and cobalt ions. This process involved non-covalent interactions such as electrostatic interactions and hydrogen bonds between the constituent components, which contributed to the stability and optimal structure of the nanocomposite. The structural and chemical properties of this nanocomposite were confirmed using characterization techniques such as infrared spectroscopy, X-ray diffraction, elemental analysis, and field emission scanning electron microscopy. The results of electrochemical eva‎luations showed that the Ni₃C/GO/Co²⁺ nanocomposite has good capacitance and cyclic stability (4000 cycles), especially at low current densities where higher capacitance was observed (2711.892 Farads/gram at 2 A current). The findings of this research can be used as a basis for further development of nanostructured materials in areas related to energy storage and help to improve existing technologies in this field.
