  Abstract

Three-dimensional (3D) conductive carbon aerogels, prepared through high-temperature pyrolysis of biomass or polymer aerogels, have garnered significant attention from researchers as electrode materials due to their unique 3D carbon framework, ultra-low density, excellent electrical conductivity, and large specific surface area. Poly(p-phenylene benzobisoxazole)/carbon nanotube (PBO-NF/CCNT) carbon aerogel films with excellent electrical conductivity were prepared by combining PBO-NF with CCNT, followed by freeze-drying and carbonization. When the CCNT content was 20% and the carbonization temperature was 900 °C, the obtained carbon aerogel film exhibited high specific surface area (174.64 cm2/g), which was favorable for the ion transport in the electrolyte. The carbon aerogel film showed large specific capacitance (212 F/g), high coulombic efficiency, and remarkable stability of the electrode. In addition, when the current density was increased from 1 to 10 A/g, the capacitance retention was above 91% and remained at 96.2% after 10,000 cycles.
