Synthesis of Spherical Carbon Nanoparticles via Sol-Gel and their Electrochemical Properties in Electrical Double Layer Capacitor

Abstract:

Spherical carbon nanoparticles were prepared by the polycondensation of resorcinol and formaldehyde using sol-gel method in the presence of cetyltrimethylammonium bromide (CTAB) and subsequent carbonization. Addition of carbon nanotubes (CNTs) in the precursor solution resulted in CNT/carbon porous composites. The effect of carbon nanotubes (CNTs) on the microstructure, pore structure and electrical double layer capacitance of CNT/porous carbon composites was examined based on the field emission scanning electron microscope, transmission electron microscope observation, N2 isothermal adsorption, cyclic voltammetry and charge/discharge tests. The results showed that 20% CNT addition had little effect, but 50% CNT addition significantly changed the microstructure and pore distribution, and charge/discharge properties.
