“…From this point of view, some strategies can be directly transferred from those designed for graphite. For instance, water-soluble binders such as CMC, [32][33][34] PAA, [35,36] Na-alginate, [37,38] have also shown effectiveness in improving the electrochemical performance of LTO. An enhanced binding strength/adhesion, compared to the PVDF binder, can be achieved with those binders.…”

Polymer binders as a critical component in rechargeable batteries provide the electrodes with interconnected structures and mechanical strength to maintain the electronic/ionic transfer during battery cycling. The conventional binders, such as polyvinylidene fluoride (PVDF), are not ideal candidates due to their relatively low adhesiveness, weak mechanical strength, and poor functionality for high‐energy‐density batteries with a thick electrode and/or a high‐capacity electrode. Nevertheless, the binder has not yet received the attention that reflects its importance in batteries. The requirements of high energy density batteries make essential the exploration of advanced polymeric binders, which possess particular functions. In this review, state‐of‐the‐art binder design strategies are sorted in terms of the challenges of various electrodes (anodes and cathodes for lithium ion batteries (LIBs) and sulfur cathodes for Li–S batteries), which have been commercialized or have the potential for practical cells. A deep insight into how the polymeric binders improve the cell performance and the design principle of new binders is also provided. Finally, a perspective on the direction of future binder development for high‐energy‐density batteries with long cycle life is presented.

“…Both Garcia et al [ 21 ] and Cuesta et al [ 22 ] studied alginate suspensions as binders for LIBs but used graphite as electrode material. Phanikumar et al [ 23 ] investigated SA and polyvinyl alcohol as aqueous-based binders for LTO anodes but did not present rheological properties [ 23 ]. As mentioned above, with an increasing demand for LIBs, cell chemistries besides graphite on the anodic side are of strong interest for futural developments.…”

Rheological Properties of Aqueous Sodium Alginate Slurries for LTO Battery Electrodes

et al. 2021

Rheological properties of electrode slurries have been intensively studied for manifold different combinations of active materials and binders. Standardly, solvent-based systems are under use, but a trend towards water-based electrode manufacturing is becoming more and more important. The different solvent is beneficial in terms of sustainability and process safety but is also accompanied by some disadvantages such as extraction of residual humidity and a higher complexity concerning slurry stability. Li4Ti5O12 (LTO) active material provides good long-term stability and can be processed in aqueous solutions. Combining the LTO active material with sodium alginate (SA) as a promising biobased polymer binder reveals good electrochemical properties but suffers from bad slurry stability. In this work, we present a comprehensive rheological study on material interactions in anode slurries consisting of LTO and SA, based on a complex interaction of differentially sized materials. The use of two different surfactants—namely, an anionic and non-ionic one, to enhance slurry stability, compared with surfactant-free slurry.

“…There has been unprecedented interest in the usage of the alginate toward different applications due to its unique valuable properties, such as its sustainability, biodegradability, biocompatibility, high hygroscopicity, flame retardancy, antimicrobial properties, and excellent ion adsorption [14][15][16]. It has been used in different forms, such as nanoparticles, microparticles, microspheres, and nanofibers, and it is widely applied in the food, textile, and biomedical industries as well as in bioremediation [17].…”

Electrospun Alginate Nanofibers Toward Various Applications: A Review

et al. 2020

View full text Add to dashboard Cite

Alginate has been a material of choice for a spectrum of applications, ranging from metal adsorption to wound dressing. Electrospinning has added a new dimension to polymeric materials, including alginate, which can be processed to their nanosize levels in order to afford unique nanostructured materials with fascinating properties. The resulting nanostructured materials often feature high porosity, stability, permeability, and a large surface-to-volume ratio. In the present review, recent trends on electrospun alginate nanofibers from over the past 10 years toward advanced applications are discussed. The application of electrospun alginate nanofibers in various fields such as bioremediation, scaffolds for skin tissue engineering, drug delivery, and sensors are also elucidated.
