In the field of supercapacitors (SCs), hierarchically porous carbon materials have gained attention as their large surface area and facile ion transport which can provide high-performance in energy application. So, we report new form of three-dimensional (3D) hierarchically structured electrode with micro-, meso-, and macropores. This well-organized structure based on polymer of intrinsic microporosity (PIM) derivative, termed PIM-EA-TB (PIM composed of ethanoeanthracene (EA) by Tröger base (TB) components) was prepared from nonsolvent-induced phase separation (NIPS) and subsequent carbonization. Through this process, a hierarchical porous structure with large surface area of 1966 m2 g−1 and a superior electrical conductivity of 83.6 S cm−1 is formed. Such structuring offers 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. |
