1. An AC-supercapacitor comprising:
(a) a pair of carbon nanofiber network (CNN) electrodes, wherein each of the CNN electrodes in the pair of CNN electrodes comprises a CNN material comprising carbonized cellulose;
(b) a separator to separate the electrodes; and
(c) electrolytes between the electrodes, wherein the AC-supercapacitor is operable for running at frequencies of at least 0.1 kHz.
