Abstract
The need for efficient energy storage and clean energy alternatives is one of the biggest concerns in the modern world. The need can be met through the application of energy storage devices such as supercapacitors, batteries, fuel cells and other energy storage devices. Supercapacitors are devices dedicated to energy storage.
 In this study, graphene oxide/SnO composite materials were obtained by using acetone, ethyl alcohol, 2- Methoxyethanol, pure water solvents. SnO nanoparticles salts used in making composite materials were produced using the sol-gel method. Graphene oxide (GO) used to obtain the composite material was synthesized using the Hummers method. XRD, SEM, FT-IR, analyzes were applied to the obtained samples. Electrode construction was carried out for supercapacitor applications by using metal oxide and graphene oxide doped composite materials obtained by using different solvents. Electrochemical measurements of the produced electrodes were performed by cyclic voltammetry (CV) and the capacitance curves and impedance spectrometers of the electrodes were determined.
