In this work, the synthesis and characterization of reduced graphene oxide (rGO) in a three-electrode system and the synthesis and characterization of rGO paper were carried out. The goal of the work was to obtain a material that is suitable for zinc deposition, which would serve as an anode in a hybrid supercapacitor. For this purpose, rGO/20%CB paper containing carbon black (CB) was prepared. The same material was also used as an anode in a zinc ion battery with rGO/20%V2O5 paper as a cathode. Characterization of supercapacitors and batteries was carried out by CV, CA and EIS methods. Current peaks corresponding to zinc deposition/dissolution and current peaks corresponding to the redox reaction of V2O5 were recorded. The electrical conductivity of rGO/20%CB paper was was found to be 6.59 Scm^-1. The specific capacitance values of the hybrid supercapacitor range from 34.18 to 41.81 F g^-1. The specific capacity values of the battery (Zn/(rGO/50%V2O5) range from 41.79 to 75.62 mA h g^-1, while for the battery (rGO Zn/(rGO/50%V2O5)) they range from 18, 05 to 31.86 mA h g^-1. In addition to testing supercapacitors, this investigation also included characterization of electrodes (rGO, rGO/10%CB, rGO/20%CB and rGO/20%V2O5) by methods of cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in three-electrode system. GO reduction was performed using the chronoamperometry (CA) method, and zinc deposition on rGO and rGO/CB layers was performed using the CV method.
