Activated carbon from polymers for energy storage applications

The world’s energy demand is increasing significantly due to population growth and industrial evolution. It raised interest in the efficient energy storage device’s research and design. This can be achieved through designing and developing novel electrode materials for high electrochemical capacitor performance. The data focuses on a synthesis of highly porous carbon derived from cross-linked polymers with improved electrochemical properties for sustainable and renewable energy storage device electrodes. It highlights successful approaches developed to enhance their electrochemical properties through the incorporation of two-dimensional materials reduced graphene oxide, a nitrogen-phosphorous dual-doping route and transition metal cobalt incorporation into the porous carbon from cross-linked polymers polyvinyl alcohol and polyvinyl pyrrolidone. The electrochemical performance of symmetric devices in neutral 2.5 molar potassium nitrate aqueous electrolytes within the cell potential of 1.6 V, revealed good specific energy and power in the range of 19.5 to 32.0 W h kg-1 and 400 to 401 W kg-1, respectively. Thus, doped porous carbon from cross-linked polymers is a promising electrode material for wide use in energy storage systems.
