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.

“…For the polymeric binder, this can be used to determine the stability if no decomposition reactions are observed. This may be accomplished by coating the pristine polymer onto the current collector and assembling a two-electrode cell with lithium metal [ 28 , 29 , 30 ]. Then, cyclic voltammograms for several cycles can be collected to determine if the binder contributes irreversibly to the faradaic current response, which could indicate degradation over the course of cycling.…”

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.

“…The polyimine binder by molecular simulations and atomic force microscope test to evaluate the adhesion force has reported. [ 66 ] The results show that the NH bonds are more stable than the aromatic CH bonds, but large number of CH bonds possessing the physical adsorption with hydrogen bonds between the polyimine chains and the surface of Si. The results indicate that compared with the interactions between other binders (PAA, CMC, and PVdF) and Si, the higher adhesion force exists between the polymeric materials and surface of Si, which can accommodate the dramatic volume changes during the repeated electrochemical process.…”

The electrode materials are the most critical content for lithium‐ion batteries (LIBs) with high energy density for electric vehicles and portable electronics. Considering the high abundance, environmental friendliness, low cost, high capacity, and low operation potential of silicon‐based anode, it has been intensively studied as one of the most promising anode materials for high‐energy LIBs. However, the widespread application of silicon anode is impeded by the poor electrical conductivity, large volume variation, and unstable solid–electrolyte interfaces films. In the past decade, significant efforts have been demonstrated to tackle these major challenges toward industrial applications. Herein, the focus is on combining with advanced structure like nanostructure and composite with other materials, exploring various new polymer binders, improving electrolyte, different prelithiation strategies, and Si/graphite design to meet commercialization requirements, particularly summarized the progress on areal capacity, initial Coulombic efficiency, and cost. Finally, the guidelines and trends for practical silicon electrodes are presented based on the recent reports.
