“…Previous studies have shown that catechol groups have high adhesiveness to various surfaces, which is beneficial for anode cycling performance. Herein, we evaluated the adhesion of these several binders to the current collector by 180° peeling test . As the Figure A demonstrated, PPP binder provides a higher adhesion force (4.2 N), compared with PVA (3.9 N) and PVA‐PEDOT : PSS (3.8 N).…”

Silicon is considered to be one of the most promising anode materials for lithium-ion batteries due to its high capacity. But the silicon anodes undergo huge volume changes during the charge and discharge process, leading to fast capacity fade of Si anodes. To solve this problem, we design a ternary polymer binder composed of poly (vinyl alcohol), poly(dopamine hydrochloride) and poly(3,4-ethylenedioxythiophene):poly (styrene sulfonate) for Si anodes. In this polymer composite binder, polydopamine and poly(vinyl alcohol) exhibit strong adhesion with the silicon particles and the copper foils. Additionally, poly (vinyl alcohol) compounded with poly (dopamine hydrochloride) shows high stretchability up to 243.7 %, which benefits for buffering large volume change of Si anodes during cycling. The conducting poly (3,4-ethylenedioxythiophene) : poly (styrene sulfonate) in this binder improves the rate performance. Using this multi-functional binder, the Si anodes show excellent cycling stability even under high Si mass loading.

“… 138 The glycerol crosslinked PEDOT: PSS (GP) binder showed greatly enhanced peeling force and superior conductivity, leading to improved cycling and rate performances (1951.5 mA h g −1 after 200 cycles at 0.5 A g −1 and 804 mA h g −1 at a high current of 8.0 A g −1 ) of SiNP anodes containing no conductive additive. Maleic anhydride crosslinked corn starch 139 or CMC 140 binders have been demonstrated to be promising binders for the Si‐based anodes (Figure 12B). Besides, Song et al employed the inorganic sodium borate to crosslink CMC, making the obtained binder with strong ability to buffer the volume change of Si particles and maintain the integrity of overall electrode (Figure 12C).…”

Conventional lithium‐ion batteries (LIBs) with graphite anodes are approaching their theoretical limitations in energy density. Replacing the conventional graphite anodes with high‐capacity Si‐based anodes represents one of the most promising strategies to greatly boost the energy density of LIBs. However, the inherent huge volume expansion of Si‐based materials after lithiation and the resulting series of intractable problems, such as unstable solid electrolyte interphase layer, cracking of electrode, and especially the rapid capacity degradation of cells, severely restrict the practical application of Si‐based anodes. Over the past decade, numerous reports have demonstrated that polymer binders play a critical role in alleviating the volume expansion and maintaining the integrity and stable cycling of Si‐based anodes. In this review, the state‐of‐the‐art designing of polymer binders for Si‐based anodes have been systematically summarized based on their structures, including the linear, branched, crosslinked, and conjugated conductive polymer binders. Especially, the comprehensive designing of multifunctional polymer binders, by a combination of multiple structures, interactions, crosslinking chemistries, ionic or electronic conductivities, soft and hard segments, and so forth, would be promising to promote the practical application of Si‐based anodes. Finally, a perspective on the rational design of practical polymer binders for the large‐scale application of Si‐based anodes is presented.

“…Failure of the binder may result in cracks forming due to internal stress caused by volume changes during lithiation. This would lead to a loss of interparticle contact, electrical isolation of the active material, and result in a significant decrease of capacity, particularly within the initial cycles [ 31 , 36 , 42 , 45 , 46 , 47 , 48 , 49 ].…”

Binders play an important role in electrode processing for energy storage systems. While conventional binders often require hazardous and costly organic solvents, there has been increasing development toward greener and less expensive binders, with a focus on those that can be processed in aqueous conditions. Due to their functional groups, many of these aqueous binders offer further beneficial properties, such as higher adhesion to withstand the large volume changes of several high-capacity electrode materials. In this review, we first discuss the roles of binders in the construction of electrodes, particularly for energy storage systems, summarize typical binder characterization techniques, and then highlight the recent advances on aqueous binder systems, aiming to provide a stepping stone for the development of polymer binders with better sustainability and improved functionalities.
