Supercapacitors are growing in popularity due to their cycling stability, quick charge-discharge rates, and high power density. These devices rely heavily upon the types of materials used within them. Many researchers agree that carbon-metal oxide nanocomposites are well performing electrode materials. The present study explores synthesis and application of nanoporous NiO/carbon as electrode materials in supercapacitor study. NiO was chosen because it has been shown to produce a synergistic effect when combined with carbon, creating a more stable electrode with higher conductivity. One pot hydrothermal method was employed to synthesize NiO/carbon nanocomposites. Poly(styrene-p-sodium) sulfonate was used as the template and structure directing agent. The porosity and connectivity of pores of nanocomposites will be tuned by using secondary surfactant. We believe that the diffusion of electrolyte and conductivity of electrode materials will be highly improved by controlling pore size distribution and pore connectivity.
