“…With the constant development of new battery systems and the demand for higher energy densities and better lifetimes, novel binder polymers are continuously being developed and investigated. For example, Yi et al [ 94 ] have developed an aqueous-processable polymer, chitosan sulfate ethylamide glycinamide (CSEG), by conjugating acryloyl glycinamide to chitosan sulfate to combine the benefits from these two components. The sulfate group of chitosan sulfate improved the aqueous solubility and helped to trap lithium disulfides to prevent their dissolution into electrolyte and protect from the shuttle effect in Li-S batteries.…”

Binders play an important role in electrode processing for energy storage systems. While conventional binders often require hazardous and costly organic solvents, there has been increasing development toward greener and less expensive binders, with a focus on those that can be processed in aqueous conditions. Due to their functional groups, many of these aqueous binders offer further beneficial properties, such as higher adhesion to withstand the large volume changes of several high-capacity electrode materials. In this review, we first discuss the roles of binders in the construction of electrodes, particularly for energy storage systems, summarize typical binder characterization techniques, and then highlight the recent advances on aqueous binder systems, aiming to provide a stepping stone for the development of polymer binders with better sustainability and improved functionalities.

“…In addition to the carboxylate functionality, amine functionalities may also support binding properties. Furthermore, functionalized chitosan‐based binders with different carboxylate or amide side chains were introduced. Crosslinking of chitosan chains was shown to increase stability, and grafting natural rubber as side chains helped to increase flexibility …”

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.

“…To improve its PS trapping capabilities, the amine groups of chitosan were substituted with acryloyl glycinamide and nitrocatechol. [ 51,52 ] Deng et al. introduced a polyphosphate cross‐linked chitosan ethylamide carbamide as an advanced binder design above the modified functional group, which was a dual‐cross‐linked network capable of providing outstanding affinity with PSs to alleviate the shuttle effect while possessing robust mechanical strength to stabilize the electrode.…”

Alkali metal–chalcogen batteries (ACBs) have attracted significant attention as next‐generation energy storages because of high energy density and reasonable cost as compared to the up‐to‐date lithium‐ion batteries. Nevertheless, their practical applications are harshly inhibited by some drawbacks, such as shuttle effects resulting from dissolved polysulfides and polyselenides, chalcogen volume expansion, and dendrite growth on metal anodes. Functional components, such as chalcogen host, binder, and interlayer, using various polar materials have been introduced to address these issues. Among them, bio‐derived materials are regarded as novel eco‐friendly alternatives. In this report, the authors focus on the unique physical/chemical/environmental properties of bio‐derived materials used in ACBs, including active host materials, polymer binders, separators, and additives. The authors hope that the present report can provide some new insights and directions for future research on high‐performance ACBs.
