| Abstract Scope |
In today’s global push for a greener future, developments in energy storage mechanisms are invaluable. Since their conception, supercapacitors have drawn special interest because of their desirable combination of the high energy density of batteries and the high power density of capacitors. This work focuses on applying lignin, an abundant biopolymer coproduct of the pulp and paper industry, as supercapacitor electrodes. It also introduces the novel use of iron-(iii)-oxide-functionalized, lignin-derived fibers as supercapacitor electrodes. In this work, lignin fibers were thermostabilized, carbonized, and activated to create a hierarchical porous
network. The resulting fibers were then functionalized with iron (iii) oxide nanoparticles to
increase their redox potential and improve capacitance. After activation, process-structure-property-performance relationships were studied by quantifying the BET surface area, analyzing
mat morphology using scanning electron microscopy, and evaluating electrochemical
performance using cyclic voltammetry and chronopotentiometry. BET calculations revealed
gains in surface area from 544 to 746 m2 g-1. |
