Summary: In this study, a one-dimensional RuO2-N-doped carbon (1D-RuO2/C) composite is synthesized and demonstrated for supercapacitor application. The 1D-RuO2/C composite exhibits a specific capacitance of 671 F/g and retains 93.46% of its capacitance after 5000 cycles at 5 A/g current. An asymmetric supercapacitor (ASC) device, constructed using 1D-RuO2/C as the positive electrode material, shows a specific capacitance of 53 F/g, a power density of 751.66 W kg-1, and an energy density of 16.71 Wh kg-1. The ASC maintains approximately 98.65% of its initial value at 10 A/g discharge current. The high electrochemical activity of the 1D-RuO2/C composite is attributed to its 1D morphology, high surface area, and synergistic interaction between RuO2 and carbon support. The researchers hope that this composite material will find applications in energy storage systems.
