Preparation of Co3O4 doped resorcinol formaldehyde xerogels and their supercapacitor performance

Abstract

This study successfully performs supercapacitor performances of cobalt oxide (Co₃O₄)-doped resorcinol formaldehyde (RF) xerogels. The results reveal a maximum specific capacitance (CS) value of 135.1 Fg^− 1 for the 25%-Co₃O₄ doped RF xerogel electrode at 0.1 Ag^− 1 current density, indicating a promising performance. The maximum energy density is 31.39 Whkg^− 1 for the 25% Co₃O₄-doped RF xerogel electrode at 0.1 Ag^− 1 current density, suggesting a high potential for energy storage. The maximum power density is 744.33 Wkg^− 1 for the 50% Co₃O₄ doped RF xerogel electrode at 0.4 Ag^− 1 current density, demonstrating a significant power output.
