“…They are generally fabricated by thermal treatment of electrospun precursor nanofibers such as polyacrylonitrile (PAN), polybenzimidazole (PBI) [ 3 ], lignin [ 4 ], and cellulose [ 5 ]. Among precursors, aromatic polyimides are good precursor candidates due to their high thermal stability and well-defined molecular structure, and they have been mainly investigated as carbon molecular sieve membranes for gas separation [ 6 , 7 , 8 , 9 , 10 , 11 ]. The molecular structure of polyimides can be controlled by the selection of dianhydride and diamine, which is crucial to determine carbonization behavior.…”

Porous carbon nanofibers (CNFs) with high energy storage performance were fabricated with a single precursor polymer, 6FDA-TFMB, without the use of any pore-generating materials. 6FDA-TFMB was synthesized, electrospun, and thermally treated to produce binder-free CNF electrodes for electrochemical double-layer capacitors (EDLCs). Highly porous CNFs with a surface area of 2213 m2 g−1 were prepared by steam-activation. CNFs derived from 6FDA-TFMB showed rectangular cyclic voltammograms with a specific capacitance of 292.3 F g−1 at 10 mV s−1. It was also seen that CNFs exhibit a maximum energy density of 13.1 Wh kg−1 at 0.5 A g−1 and power density of 1.7 kW kg−1 at 5 A g−1, which is significantly higher than those from the common precursor polymer, polyacrylonitrile (PAN).
