“…Subsequently, we compared the cell performance of the Si anode made using the xPAA-B-DA binder to the performances of other Si anodes prepared with a variety of previously reported aqueous polymer binders. − The Si particle size, electrode mass ratio, mass loading, and current density constitute some of the parameters that have a major impact on the Si anode cell performance; thus, the comparison was conducted considering these factors (Figure ).…”

“…Consequently, there has been a growing interest in the development of environmentally friendly binders and solvents for LSBs. In recent years, a range of water-based binders, such as LA132, [126] PVP-, [127] PVA-, [97] PAA-based binders, [5,128] and poly(methyl vinyl ether-alt-maleic acid) (PMVEMA), [129] have been proposed for sulfur cathodes due to the avoidance of adverse effects associated with organic solvents. Water-based binders are typically insoluble in organic electrolytes, thereby preserving electrode stability.…”

Lithium‐sulfur batteries (LSBs) are regarded as a highly promising next‐generation energy storage technology due to their exceptional theoretical capacity and energy density. However, the practical application of these batteries is hindered by several challenges, including significant volume change of active materials, severe shuttle effect of lithium polysulfides, inadequate electronic and ionic conductivity, and safety concerns. These issues are particularly pronounced in cathodes with high sulfur loading, which are essential for the effective implementation of LSBs. Binders are an essential constituent of sulfur cathodes, and they perform a crucial function in enhancing the efficacy of LSBs, particularly when subjected to high sulfur loading. A considerable amount of research has been conducted to investigate the potential of multifunctional binders to tackle the aforementioned challenges associated with LSBs. This article provides a comprehensive overview of the various roles that advanced multifunctional binders play in LSBs, including but not limited to preserving electrode integrity, capturing lithium polysulfides, regulating Li2S deposition, accelerating reaction kinetics, enhancing ionic and electronic conductivity, promoting sulfur cathode safety, and safeguarding the environment. Additionally, the paper outlines the challenges and prospects for future research endeavors aimed at creating innovative multifunctional binders and improving the overall performance of LSBs.

“…The dynamic crosslinking process achieves close interaction of the β-CDp/6AD binder and improves the cycling performance of the Si anode (90% capacity retention about 1600 mAh g −1 after 150 cycles at 1.5 A g −1 ). In 2022, Zheng et al used linear PAA and partially neutralized sodium polyacrylate (PAAS) as the binder framework, and esterified β-CDp with the carboxyl groups on the framework to form a stable chemical bond (ester, ionic) and hydrogen bonds to synergistically design a three-dimensional cross-linked network structure to obtain PAAS-β-CDp-PAA binder [39] (Figure 20a). This PAAS-β-CDp-PAA binder can enhance the adhesion between the active substance and the current collector.…”

The use of silicon (Si) as a lithium-ion battery’s (LIBs) anode active material has been a popular subject of research, due to its high theoretical specific capacity (4200 mAh g−1). However, the volume of Si undergoes a huge expansion (300%) during the charging and discharging process of the battery, resulting in the destruction of the anode’s structure and the rapid decay of the battery’s energy density, which limits the practical application of Si as the anode active material. Lithium-ion batteries’ capacity, lifespan, and safety can be increased through the efficient mitigation of Si volume expansion and the maintenance of the stability of the electrode’s structure with the employment of polymer binders. The main degradation mechanism of Si-based anodes and the methods that have been reported to effectively solve the Si volume expansion problem firstly are introduced. Then, the review demonstrates the representative research work on the design and development of new Si-based anode binders to improve the cycling stability of Si-based anode structure from the perspective of binders, and finally concludes by summarizing and outlining the progress of this research direction.
