“…Such nanopores afford a uniform metal‐ion flux at the electrode‐electrolyte interface during cycling, alleviating concentration gradients build up to provide a stable lithium deposition/stripping which ultimately avoids dendrite formation. [ 67,90,100,180 ] 3) Because of the tendency of biopolymers to ionic crosslinking and hydrogen bonding, these macromolecules have been effectively used to develop GPEs and SPEs which act as a physical barrier for the growth of dendrites. [ 81,181 ] (4) Biopolymers have been used as a platform material to develop GPEs having high ion transference numbers, preventing competitive transport of anions and cations in binary electrolytes and thus providing a homogeneous and dendrite‐free metal deposition.…”

“…[89] Using sodium alginate, Song et al prepared a composite membrane with attapulgite (ATP), which was processed via NIPS (water as the solvent and N-methyl-2-pyrrolidone as the non-solvent) to obtain a thermally stable porous separator for LIBs. [90] Owing to a large specific surface area of 163.3 m 2 g −1 and a mesoporous structure which facilitates electrolyte absorption via capillary action, the composite membrane showed an electrolyte uptake of up to 420% and an ionic conductivity of 1.15 mS cm −1 . In a Li/LiFePO 4 cell, the membrane delivered a remarkable performance -82% retention after 700 cycles (115 mAh g −1 ) at a 5C rate.…”

Rechargeable batteries are ubiquitous, and their usage is projected to grow tremendously over the years. They are vital to curbing the fossil fuel dependency and are destined to play a significant role in the future energy landscape. However, rising demand will eventually strain raw material resources, and potentially cripple the development and deployment of associated technologies. In this regard, alongside materials and methods involving sustainable resources, greener manufacturing and recycling potential, renewable resource derived biodegradable materials, i.e., natural biopolymers-are attracting interest for sustainable and eco-friendly future batteries. While they are being studied for nearly all aspects of a battery cell development, their exploration as an electrolyte component has been the subject of widespread investigations. These studies include, but are not limited to, their utilization as the building block for electrolyte wettable and more thermally resistant separators, as an alternative to synthetic polymers in gel polymer and solid polymer electrolytes, and as functional membranes to inhibit the loss of electroactive species in diverse battery chemistries. Here, a summary of natural biopolymer-based electrolytes and separators development that incorporate novel concepts is presented to tackle specific issues in various battery systems and future perspective underpinning their further advancement.

“…Similarly to binder materials (see above), alginates are another important class of biopolymers that are used in electrolytes and separators . In energy storage device that are completely derived from biomass, they may serve not only as a binder and precursor for carbon electrodes, but also as the gel electrolyte and separator .…”

“…In general, similarly to cellulose‐based separators/electrolytes, blending or compositing is a widely employed approach to optimize performance. Combinations with inorganic filler materials or thermally stable polymers are especially appealing, as such combinations may be inherently stable and do not shrink upon heating, improving the safety of batteries by prevention of short‐circuit faults . In general, solid or gel‐like electrolytes/separators are complex materials in which the exact composition often determines the applicability.…”

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.

Aiming to improve the sustainability of materials for lithium‐ion batteries (LIBs), this work reports on the development of novel membranes based on iota‐carrageenan biopolymer and their suitability as separator in LIBs applications. The membranes are prepared by freeze‐drying and its morphology, thermal, mechanical, and electrochemical properties are evaluated as a function of polymer concentration in the solution. Porous membranes with a degree of porosity above 90% and different interconnected pore sizes between 50 and 70 µm for both polymer concentrations are obtained. The electrochemical parameters of the membranes are influenced by the carrageenan polymer concentration, being 1.34 mS cm‐1, 3, 7, and 0.48 for ionic conductivity, tortuosity, MacMullin number, and lithium transference number, respectively, for the membrane prepared from the 4 wt% carrageenan content solution. The half‐cells cathodic prepared with the developed membranes show good cyclability and rate capability. The discharge capacity values obtained with the membrane prepared from 4 wt% carrageenan content are 145 and 25 mAh g‐1 at C/10‐ and 1C‐rates, respectively, demonstrating excellent battery cycling performance and long‐term stability. Thus, this work demonstrates that iota‐carrageenan biopolymer membranes developed by freeze‐drying can be used as separators for a next generation of more sustainable batteries.
