Abstract

A composite electrode consisting of hybrid nanonet/nanoflower NiO deposited on carbon fiber paper scaffolds demonstrates a much-improved areal capacitance (0.93 F cm−2) while maintaining high rate capability and excellent cycling life. These performance characteristics are attributed to the unique electrode architecture and the nanostructures of NiO. While the nanonet NiO with a high surface area greatly facilitates the redox reactions for charge storage, the porous nanoflowers further extend the active sites for the redox reactions, leading to fast Faradic reactions for efficient energy storage.
