“…A handful of reports exists where organic electrodes are combined with a solid electrolyte with greatly enhanced cyclic performance. 55,[107][108][109][110][111][112][113][114][115] In this chapter, the two main types and the biggest problems of solid-state electrolytes are briey accounted followed by a discussion of how the organic materials could t together with these electrolytes.…”

“…109 Applying solid electrolytes with N-type materials is relatively straightforward and a handful of reports already exist where polymer or glass type solid electrolytes are used with N-type organics. 55,[107][108][109][110][111][112][113][114][115] This approach also allows the use of lithium anode, which solves the problem of N-type organic materials being in a non-lithiated state. The P-type organics are much harder to combine with a solid electrolyte.…”

“…Materials based on cellulose may be especially promising, as cellulose‐based separators are already being commercially applied in alkaline batteries. Consequently, such separators have been investigated in combination with all kinds of electrodes, including not only inorganic but also organic electrode materials . However, limitations from high water content, stability problems, and safety issues have prevented commercial application in lithium‐ion batteries to date .…”

“…When cellulose is used as a support for another separator material, the properties of that other material might dominate or, at the very least, influence the performance, mitigating the adverse properties of cellulose but simultaneously decreasing the overall sustainability in cases where the other material is not biomass‐derived . Composite or hybrid separators based on combinations of cellulose‐derived materials with other materials have been described, in which additives enhance the material's properties .…”

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.

“…Fei et al. studied poly(propylene carbonate)‐ and KFSI‐based electrolytes, supported by nonwoven cellulose for organic potassium‐metal batteries . Despite a rather low ionic conductivity of about 1.4×10 −2 mS cm −1 , the resulting cells, incorporating 3,4,9,10‐perylenetetracarboxylic dianhydride (PTCDA) as a cathode, provided a specific capacity of 118 mAh g −1 at a low current density of 10 mA g −1 .…”
