Abstract
A flexible all-solid state supercapacitor is provided that includes a first electrode and a second electrode, and a flexible nanofiber web, where the flexible nanofiber web connects the first electrode to the second electrode, where the flexible nanofiber web includes a plurality of flexible nanofibers, where the flexible nanofiber includes a hierarchal structure of macropores, mesopores and micropores through a cross section of the flexible nanofiber, where the mesopores and the micropores form a graded pore structure, where the macropores are periodically distributed along the flexible nanaofiber and within the graded pore structure.
