High-rate hybrid supercapacitor |
| abstract |
The high-rate hybrid supercapacitor (HSC) has a positive electrode made from copper oxide (CuO)-cobalt oxide (CoO) core-shell nanocactus-like heterostructures produced on a nickel foam substrate, a negative electrode made by coating nickel foam with graphene ink, and a separator of cellulose paper. The heterostructures each have a core of CuO nanoflakes and a shell of CoO nanoneedles extending from the nanoflakes. The HSC achieves a specific capacity of 173.9 mA h g −1 at 1 A g −1 and long cycle life with 94% retention over 5000 cycles at 4 A g −1 , and also exhibits a stable operating voltage window of 1.6 V, energy density of 56.5 W h kg −1 , and cycling stability of 98.8% retention with coulombic efficiency of 98.7% over 4000 cycles. |
