Formatted 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 387Fg-1 at a current density of 1mAcm-2, with a high energy of 19Whkg-1 and power density of 1713Wkg-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.
