Supercapacitors have attracted great attention due to their high power density, rapid charge/discharge cycles and long life-time. Currently, these devices are limited by their cost and scalability for commercial manufacturing. Herein we introduce a cost-effective method for synthesizing a porous carbon structure with embedded graphite-encapsulated Ni nanoparticles and tunable structural properties. By varying the carbon content of precursors, utilizing monosaccharides and disaccharides, the overall surface area and pore size was optimized for maximum capacitance. The bulk structure was investigated with microscopy. Presence of Ni nanoparticles and graphite encapsulation was confirmed with XRD and is corroborated with Raman spectroscopy. This comparison was conducted using BET analysis and is correlated with cyclic voltammograms comparing the changes in Helmholtz double-layer capacitance, derived energy density and power density. These devices represent a cheap, environmentally benign approach to modern supercapacitors while simultaneously exerting control over bulk structural properties.
