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
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.
