“…The high carbon content of lignin makes it a particularly promising feedstock for carbon-based materials including carbon fibre and activated carbons. [3][4][5][6] Lignin-derived activated carbons have shown promise in a range of applications from electrode materials in supercapacitors [7][8][9][10] and batteries [11][12][13] to sorbents for the adsorptive storage of gases [14,15]. In addition, the highly aromatic structure of lignin makes it a good candidate for a sustainable replacement for phenolic resin, a crude oil-derived aromatic polymer used in the synthesis of polymeric carbons and as a thermal binder.…”

Lignin, a natural biopolymer and abundant by-product, is a particularly promising feedstock for carbon-based materials and a potentially sustainable alternative to phenolic resins, which are typically derived from crude oil. The source and method used to isolate lignin have a large impact on the thermal properties of the polymer, and can affect resultant materials prepared from lignin. Previous investigations into lignin characterisation often utilise a variety of feedstocks and isolation methods, which can make robust comparisons challenging. We present a systematic investigation into the chemical composition of lignins extracted using an identical Organosolv isolation method but from different biomass feedstocks: hemp hurds, eucalyptus chips, flax straw, rice husk and pine. We show how the aromatic structure of lignin can affect the thermal behaviour of the polymer, which correlates to the structure of resulting carbons. Carbons from lignins with a high syringyl unit content display a pronounced foaming behaviour which, on activation, results in a high-surface area material with hierarchical porosity.

“…Similarly, all kinds of biowaste have been carbonized and used as host materials in the cathodes of lithium–sulfur, lithium–selenium, or lithium–oxygen batteries. Within recent years, for example, carbons made from waste materials such as fruit stones or peels, algae, nutshells, soybean hulls, grain waste, other plant waste, saw dust, and lignin have been described in this regard.…”

“…Because of the latter, carbon as a conductive support is not mandatory, however, it helps to prevent dissolution and volume expansion issues . Impregnation of biomass‐based carbons with selenium proceeds in a similar manner to impregnation with sulfur, that is, usually by mixing both components and heating them above the melting point of selenium . Specific capacities are lower than in lithium–sulfur batteries (typically 500–700 mAh g selenium −1 , decaying by 20–50 % within the first 100 cycles), owing to the lower theoretical capacity.…”

Sustainable sources of energy have been identified as a possible way out of today's oil dependency and are being rapidly developed. In contrast, storage of energy to a large extent still relies on heavy metals in batteries. Especially when built from biomass‐derived organics, organic batteries are promising alternatives and pave the way towards truly sustainable energy storage. First described in 2008, research on biomass‐derived electrodes has been taken up by a multitude of researchers worldwide. Nowadays, in principle, electrodes in batteries could be composed of all kinds of carbonized and noncarbonized biomass: On one hand, all kinds of (waste) biomass may be carbonized and used in anodes of lithium‐ or sodium‐ion batteries, cathodes in metal–sulfur or metal–oxygen batteries, or as conductive additives. On the other hand, a plethora of biomolecules, such as quinones, flavins, or carboxylates, contain redox‐active groups that can be used as redox‐active components in electrodes with very little chemical modification. Biomass‐based binders can replace toxic halogenated commercial binders to enable a truly sustainable future of energy storage devices. Besides the electrodes, electrolytes and separators may also be synthesized from biomass. In this Review, recent research progress in this rapidly emerging field is summarized with a focus on potentially fully biowaste‐derived batteries.

“…Lignin can also be used to fabricate porous carbonaceous frameworks for the encapsulation of elemental Se as applied in high‐performance Li‐Se batteries. Composites of lignin‐derived porous carbon/Se have been fabricated and have exhibited a reversible capacity of 596.4 mA h g −1 at 0.5 C with a capacity retention of 453.1 mA h g −1 over 300 cycles . Meanwhile, a Klason lignin extracted from buckwheat husks and hydrolysis lignin have also been demonstrated to possess application potential as cathode material for a primary lithium battery .…”

Electrode and electrolyte materials with higher performance, longer life, and lower cost need to be developed, given the substantial growing demand for advanced electrochemical energy systems. Lignin, the second most abundant natural polymer, has been successfully demonstrated to be a viable precursor or feedstock for the preparation of high-performance electrochemical energy materials and components such as electrodes, electrolyte additives, membrane separators, and binders. Moreover, techno-economic analyses indicate that it is possible to prepare cost-effective carbon structures from lignin at engineering scale, in contrast with current carbon products. These facts suggest that the scalable conversion of lignin into high-value energy materials will offer a promising pathway to not only promote the utilization and valorization of lignin but also boost the development of advanced electrochemical energy systems. This review examines cutting-edge renewable energy materials derived from various lignin compounds and Review: Lignin to energy materials X Wu et al.their applications in electrochemical energy systems with an emphasis on supercapacitors, rechargeable batteries, and fuel cells. Meanwhile, this review also aims to carve out the critical barriers for lignin-derived high-performance materials for energy applications, and to identify viable approaches for the synthesis of sustainable new energy materials.
