제목 Energy storage electrodes based on NiO nanosheet grown directly on mesoporous TiN films
초록 We report fabrication of electrode consisting of NiO nanosheets (NiO-NS) grown directly on a mesoporous TiN (meso-TiN) film templated by the PVC-g-POEM graft copolymer via a solvothermal method. The interconnected mesoporous and ultrathin structure induced large surface area and effective electron pathway enhancing their specific capacitance and electrochemical properties. As TiN film prepared without the PVC-g-POEM showed low porosity, it is clear that templating by PVC-g-POEM caused high electrode performance properties of TiN film. Owing to the properties of the NiO-NS and meso-TiN heteronanostructure, the NiO-NS/meso-TiN supercapacitor exhibited a high capacitance of 104 mFcm−2) with excellent cycle stability (86% after 2000 cycles) as well as great flexibility providing an efficient way to design flexible energy storage devices.
