Pristine Lignin: A Sustainable Material for Electrochemical Energy Storage

open access: yesSusMat, Volume 5, Issue 6, December 2025.
Lignin, one of the most abundant biopolymers, can be extracted from biomass and used in its pristine form for advanced applications including batteries and supercapacitors. Its intrinsic biodegradability and carbon‐neutral lifecycle further enhance lignin's potential as a sustainable and circular material for next‐generation energy technologies ...
