Preparation of Co₃O₄ doped resorcinol formaldehyde xerogels and their supercapacitor performance

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.
