Porous N-doped carbon nanofibers derived from polydopamine are fabricated by a facile carbonized technique and a subsequent template-removing process. Superior to the other porous carbon nanomaterials that voids are directly exposed in the electrolyte, the nanopores in our designed nanofibers are confined by the inner carbon walls and outer carbon shells. The prepared porous N-doped carbon nanofibers electrode shows high reversible capacities of 1324 mAh g(-1) after 150 cycles at 0.2 A g(-1) and 780 mAh g(-1) after 500 cycles at 1 A g(-1).
