钴酸镍纳米花/活性炭纤维复合物的制备和表征及其超级电容器性能
Synthesis and Characterization of NiCo2O4 Nanoflower/Activated Carbon Fiber Composite and Its Supercapacitor Properties
摘要
Abstract
In the present work,NiCo2O4 nanowires grown directly on carbon fibers self-organize into a nanoflower morphology.The materials are prepared by hydrothermal treatment and subsequent low-temperature annealing.Field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) results reveal a hierarchical three-dimensional mesoporous structure,which facilitates ion transport and electronic conduction for fast redox reactions.As a result,the electrode achieves a respectable specific capacitance of 1626 F· g-1 at 1 A· g-1 and high rate capability (65％ retention at 10 A· g-1),so it shows promise for application in supercapacitors.关键词
