“…First reported by Milczarek and Inganäs, such electrodes have been summarized in several reviews recently . In particular, combinations with conductive polymers such as polypyrrole, polyaniline, or poly(3,4‐ethylenedioxythiophene) (PEDOT) have been described. Addition of polysaccharides for stability and binder purposes resulted in particularly sustainable electrodes .…”

Importantly, whereas guaiacol and syringol groups in lignin are oxidized during electropolymerization of aniline and EDOT in the presence of lignin, post‐synthesis oxidation is necessary in the case of pyrrole polymerization in the presence of lignin .…”

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.

“…2e). The models are based on modified Nernst-Plank-Poisson equations to describe the transport of the present species along with both hole and ion electrostatics 34 , which together describe the charging characteristics of the CNF+PEDOT:PSS electrodes for both the homogeneous and heterogeneous representations. Given the cylindrical shape of the cell, the homogeneous model ( Fig.…”

“…Such phase separation is especially the case when organic mixed ionic electronic conductors, like PEDOT:PSS, are involved. In our recent works 17,24,34 , we overcame this limitation by coupling the fermi level in the semiconductor to the electric double layer established between the electronic and ionic phases of the CP. Based on this approach, we were able to quantitatively reproduce the charging dynamics of PEDOT:PSS-based electrodes.…”

“…The SC assembly is made of PEDOT:PSS -cellulose nanofibrils composite electrodes separated by an ionic liquid (1-Ethyl-3methylimidazolium ethyl sulfate, EMIMES) soaked membrane. The theoretical model is based on our previous works 24,34 but is further developed to account for all aspects of the studied CPSC. We find that the SC characteristics cannot be reproduced by a homogeneous model but instead requires the incorporation of two phases with different ionic diffusivities.…”

Conducting cellulose composites are promising sustainable functional materials that have found application in energy devices, sensing and water purification. Herein, conducting aerogels are fabricated based on nanofibrillated cellulose and poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate, using the ice templating technique, and their bulk morphology is characterized with X‐ray microtomography. The freezing method (−20 °C in a freezer vs liquid nitrogen) does not impact the mean porosity of the aerogels but the liquid‐N2 aerogels have smaller pores. The integration of carbon fibers as addressing electrodes prior to freezing results in increased mean porosity and pore size in the liquid‐N2 aerogels signifying that the carbon fibers alter the morphology of the aerogels when the freezing is fast. Spatially resolved porosity and pore size distributions also reveal that the liquid‐N2 aerogels are more inhomogeneous. Independent of the freezing method, the aerogels have similar electrochemical properties. For aerogels without carbon fibers, freezer‐aerogels have higher compression modulus and are less stable under cycling compression fatigue test. This can be explained by higher porosity with larger pores in the center of liquid‐N2 aerogels and thinner pore walls. This work demonstrates that micro‐CT is a powerful tool for characterizing the morphology of aerogels in a non‐destructive and spatially resolved manner.
