Abstract

Crosslinking lignin on high surface area active carbon using glyoxal as a green crosslinker leads to truly sustainable electrodes with improved performance.

Highlights

  • Lignin, being a major constituent of all rooted plant biomass and the most abundant aromatic biopolymer on earth, is a widely available yet currently hardly used resource

  • Lignin is a promising material to be used in sustainable energy storage devices

  • It may act as an active component due to hydroquinone motifs or as a binder in electrodes

Summary

Introduction

Lignin, being a major constituent of all rooted plant biomass and the most abundant aromatic biopolymer on earth, is a widely available yet currently hardly used resource (except for combustion). We fabricated electrodes from this crosslinked lignin-based material and high surface area active carbon and investigated charge storage by cyclic voltammetry.
