Abstract
We report a simple, cost-effective, and potentially scalable approach for the fabricating hierarchically porous CoOOH thin-film supercapacitors by combining a soft-templating and a chemical-bath deposition (CBD) method. The prepared electrode materials exhibit uniform morphology and highly ordered macropores, achieving a maximum specific capacitance of 387 F g−1 at a current density of 1 mA cm−2, with a high energy of 19 Wh kg−1 and power density of 1713 W kg−1. In addition, the porous CoOOH electrodes show good stability with a cycling efficiency >90 % after 5000 charge–discharge cycles, which could lead to the generation of novel energy-storage devices with better efficiencies.
