文摘
- •
Nano-nickel is deposited by flowing deposition method as the current collect.
- •
Active materials Co(OH)2 are deposited on nanographene (NG) on MECN.
- •
Co(OH)2/NG can be scanned faster than Co(OH)2 in CV because of high conductivity.
- •
The Co(OH)2/NG composite exhibits a stable capacitance of 3.522 F/cm2 (880.5 F/g).
- •
The retention ratio of Co(OH)2/NG composite is 99% after 5000 cycles.
