Supercapacitors are known to be excellent candidates as a future energy storage device, with their inherent fast charge-discharge characteristics and outstanding cycle stability, but they have a room for improvement in the energy density aspect compared to other devices. The main obstacle has been optimization of nanostructured carbon electrodes, which need to be carefully designed and fabricated accordingly. Here, we report a novel and simple fabrication method to form a 3-D bicontinuous carbon nanostructure with hierarchical pores that can be precisely controlled, ideal in supercapacitor applications. The process utilizes BCPs as structure directing agents for carbon precursors, allowing precise and versatile control of both morphology and dimensions. This simple yet highly controllable process allows modifications of the electrodes to suit the application’s needs, with easy control of various features, including but not limited to: thickness, morphology, and pore sizes. |
