Abstract
We report on the design and synthesis of CFs@NiO-NSs and NiO-NSs core-shells by growing nickel oxide nanosheets (NiO-NSs) on carbon fibers (CFs), and test their applications as supercapacitors. We fabricate electrodes based upon the CFs@NiO-NSs core-shell and the NiO-NSs shell and measure their electrochemical performances. In comparison to the NiO-NSs electrode, the CFs@NiO-NSs electrode shows a more enhanced electrochemical performance with a high specific capacitance of 891.1 F g-1 at a current density of 1 A g-1, a good rate capability with 83.3% retention even at a high current density of 20 A g-1, and an excellent cycling stability by retaining 95% even after 5000 cycles. These results make the CFs@NiO-NSs a promising electrode material for high-performance supercapacitors.
