Microporous Tröger's base polymers-derived 3D porous carbon electrodes for supercapacitors |
| 초록 |
Hierarchically porous carbon material has been investigated because their large surface area and easy ion transport ensure high-performance in energy applications. We report hierarchically porous carbon based on polymers of intrinsic microporosity (PIMs) derivative, abbreviated as PIM-EA-TB, for use in high-performance supercapacitor electrodes, which is prepared via PIM-EA-TB synthesis using ethanoeanthracene (EA) involving Tröger’s base (TB) linkage formation, via nonsolvent-induced phase separation (NIPS) methods, and subsequent carbonization. Due to the synergistic effect of intrinsic micropores of PIM-EA-TB and NIPS process, the carbon material has hierarchical porous structure with high surface area of 1966 m2 g−1 and a high electrical conductivity. Such well-organized structure provides a path for facile charge transport, which leads to high specific capacitances of 46 F g−1 at 1 A g−1 and a high specific energy of 17 W h kg−1 at a specific power of 1 kW kg−1. |
