Resumen:

Lignin is the most abundant natural phenolic polymer and one of the main constituents of biomass. This compound is usually obtained from many precursors by various techniques. Lignin can be subjected to thermochemical treatments to obtain carbonaceous materials suitable to be implemented in different applications, such as supercapacitors. These thermochemical processes include hydrothermal liquefaction, pyrolysis, or gasification. Once these carbonaceous materials are obtained, they can be used in electric double-layer supercapacitors, showing adequate energy storage properties in both types of devices. All properties are thoroughly discussed through the chapter. Additionally, a comprehensive review on the computational methodologies given by ab initio and molecular dynamics formalism was also provided to elucidate the physicochemical properties of lignin. The potential of nanoporous carbon materials coming from lignin-derived biomass was also explored. Those descriptors theoretically obtained from computational techniques, related to capacitive properties, were also analyzed to be implemented in further studies. This could aid to enhance the performance of lignin-based material electrodes for energy storage devices, such as supercapacitors. © 2022 WILEY-VCH GmbH, Boschstr. 12, 69469 Weinheim, Germany.
