TL;DR: In this article, a three-dimensional macroporous carbon film composed of interwoven connected carbon fibers containing around 10wt% oxygen and 8 wt% nitrogen was synthesized by carbonizing a common livestock biowaste in the form of chicken eggshell membranes.
Journal ArticleDOI
Colossal pseudocapacitance in a high functionality–high surface area carbon anode doubles the energy of an asymmetric supercapacitor
