Nanohybridization of Ionic Liquids and Cobalt Hydroxide Nanofiber: Manipulation of Morphology and Surface Chemistry for High Performance of Pseudocapacitor |
| 초록 |
A new bottom-up self-assembly technique for the construction of the porous network structure of ionic liquid (IL) functionalized-Co(OH)2 nanofibers is reported to facilitate ion and electron transfer using a tailored favorable morphology (mesopore size: 4.8 nm, large surface area: 400.4 m2/g) and interfacial engineering. As-obtained IL-Co(OH)2 hybrids exhibited superior performance properties for a pseudocapacitor with a high specific capacitance of 859 F/g at 1 A/g, a high rate capability of ~95% retention at 30 A/g, and an excellent cycling performance of ~96% retention over 1000 cycles. |
