- Аннотация: Аннотация: In this work, the electrochemical properties of electrode coatings based on modified polyphenothiazine (PPTA) and polyphenoxazine (PPOA) and their composites with reduced graphene oxide (RGO) in an aprotic lithium organic electrolyte were studied for the first time. The specific capacitances of the polymeric coatings on AGF at comparable weights (0.20 mg) differ slightly and amount to 395–365, 250, 185 F/g for PPTA and 425, 275, 190 F/g for PPOA at charge-discharge current densities of 0.5, 1.5, 3.0 mA/cm², respectively. Depending on the coating weight on the AGF substrate, the specific weight capacitances Сw for PPOA/RGO (0.10 mg) are higher, reaching 890, 650, 510 F/g in the organic electrolyte, compared to 447–418, 265, 159 F/g for PPTA/RGO (0.17 mg). The specific surface capacitances Сs of the AGF/PPOA and AGF/PPOA/RGO electrodes are 0.166 F/cm² and 0.171 F/cm², respectively. The developed AGF/PPOA/RGO electrodes are promising for high-voltage, flexible supercapacitors.
