“…The most important classification of polysaccharides is carboxymethyl cellulose. CMC is a semi-crystalline, water-soluble, non-toxic [53,54], low-cost [55][56][57], and biodegradable material [58][59][60] with excellent film-forming ability; however, it suffers from low conductivity [61,62] and the lack of strength [63]. Extensive studies have been conducted on the CMC application in single polymer electrolyte systems, however, some problems limit its application in this field due to small elongation at break, exceptionally stiff behavior, (less than 8%), and losing the electrochemical stability required for electrochemical devices.…”

Polyvinyl alcohol/carboxymethyl cellulose (PVA/CMC) composites have attracted considerable attention due to the synergic relation between the two polymers and developing novel blends with improved properties. On one hand, PVA is a versatile polymer with higher mechanical properties compared to CMC. On the other hand, CMC has high biodegradability and biocompatibility, while suffering from poor mechanical properties. Therefore, the blending of the two polymers can help to benefit from the individual component properties. This paper has reviewed the properties and potential applications (e.g. drug delivery, food packaging, and agriculture) of the PVA/ CMC composites.

“…It is worth noting that the high water content may also be beneficial for fabrication from aqueous slurries, for example, in simple paper‐making processes . Even more importantly, for supercapacitor applications that employ aqueous electrolytes, significant water content of the separator is irrelevant—in contrast, hydrophilicity here is advantageous for optimal ion transport …”

“…For high transference numbers, increased stability, and to prevent disintegration to nanofibers, negatively charged groups may be introduced on the surface of cellulose fibers, for example, by conversion to carboxymethyl cellulose (CMC) . Consequently, besides the addition of additives, chemical modification is a widely employed tool to increase the performance of cellulose‐based separators/solid or gel‐like electrolytes.…”

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.

Electrochemical capacitors (ECs) are currently considered as advanced devices for applications in electrical vehicles and renewable energy owing to their high power density, high rate capability, exceptional durability, and reversibility compared to conventional capacitors and Li-ion batteries. [1] ECs are classified into two groups: (i) electrical double-layer capacitors (EDLCs), which store the electric charge using reversible adsorption of ions from the electrolyte onto the electrode surface; and (ii) redox or pseudocapacitors, which use fast and reversible faradaic reactions occurring at the electrode-electrolyte interface. ECs are commonly fabricated using inorganic/organic hybrid materials, such as metal nanoparticles/ nanowires (e.g., Ag, Cu), metal oxides (e.g., MnO 2 , RuO 2 ), and carbon materials (CNT, graphene) dispersed in conductive or nonconductive polymers. [2] On the other hand, in recent years, ECs have become important elements for flexible and wearable electronic devices, which are playing important roles in fields like health monitoring, artificial intelligence, sensory skin, or soft robotics. To date, many wearable devices have been successfully developed to monitor, for example, heart beat rate, glucose content in sweat, or body temperature, [3] all them requiring soft, flexible, lightweight, and comfortable energy storage systems. Within this context, ECs based on polymeric systems are particularly attractive as, in addition to the abovementioned properties, polymers can also incorporate new functionalities, such as being biocompatible, conformable, self-healing, and sustainable, to fulfill special demands. [4,5] Conducting polymer (CP)based hydrogels are ideal candidates for use in flexible ECs owing to their unique properties such as good electronic properties, tunable mechanical flexibility, and ease of processing. [4,6] In addition, hydrogel materials may have remarkable biological characteristics (e.g., self-adhesive and antimicrobial activity) for biomedical applications. [7] While many works are available in the literature about combining conducting and synthetic polymers to form hydrogels for energy storage devices, studies related to the synergistic effect between CPs and biopolymers are scarce yet. For example, lightweight hydrogels based on the macromolecular One limitation of wearable electronics, and at the same time a challenge, is the lack of energy storage devices with multiple functionalities produced using clean and environmental-friendly strategies. Here, a multifunctional conductive hydrogel containing poly(3,4-ethylenedioxythiophene) (PEDOT) and alginate is fabricated, to be used as electrodes in supercapacitors, by applying water-mediated self-assembly and polymerization processes at room temperature. The interpenetration of both polymers allows the combination of flexibility and self-healing properties within the same hydrogel together with the intrinsic biocompatibility and sustainability of such materials. Initially, PEDOT:polystyrene sulfonate and alginate a...
