Summary In this review, we highlight recent achievements of polymer binders used for Si‐based anodes in Li‐ion batteries. We classify the polymer binders, depending on their polymer structures and the function on performances of Si‐based anodes, into 3 types: cellulose‐type, conductive‐type and self‐healing‐type binders. The relationship between polymer structures and enhanced electrochemical performances of Si‐based anodes is discussed in details. We investigate how the binders make an extraordinary improvement on the specific capacity, cycling stability and rate performances of Si‐based anodes. The reasons of the noticeable effect on Si‐based anodes especially the controlling of swelling during cycling are also researched. In a word, the main aim of this review is to analyze recent research achievements and propose perspectives of polymer binders used for Si‐based anodes in promising Li‐ion batteries.

“…Some hydroxyl and carboxyl functionalized polymer materials, such as carboxymethylcellulose (CMC), polyacrylic acid (PAA) and sodium alginate can form hydrogen bonds with hydroxyl groups on the Si surface, thus having better bonding ability with Si particles. In order to further improve the stability of the Si‐based LIBs, modifying CMC, PAA, and sodium alginate polymer via crosslinking, grafting or blending are employed as effective methods. These modification methods overcome some disadvantages of single polymers and improve the electrochemical performance of the Si‐based LIBs.…”

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.

“…8). 62 NaPAA-g-CMC-Si can form multidimensional contacts with Si surface via strong hydrogen bonding and ion-dipole interactions, leading to a stronger adhesion property of NaPAA-g-CMC-Si anode compared to that of linear binder-based ones, i.e., CMC-Si and NaPAA-Si. The electrochemical tests were carried out by a galvanostatic measurement with a half-cell consisting of 60 wt% silicon nanoparticle (diameter = 50-100 nm, Si loading = 0.45 mg cm…”

The emerging era of supramolecular polymeric binders in silicon anodes

View full text Add to dashboard Cite

Silicon (Si) anode is among the most promising candidates for the next-generation high-capacity electrodes in Li-ion batteries owing to its unparalleled theoretical capacity (4200 mA h g À1 for Li 4.4 Si) that is approximately 10 times higher than that of commercialized graphitic anodes (372 mA h g À1 for LiC 6 ).The battery community has witnessed substantial advances in research on new polymeric binders for silicon anodes mainly due to the shortcomings of conventional binders such as polyvinylidene difluoride (PVDF) to address problems caused by the massive volume change of Si (300%) upon (de)lithiation. Unlike conventional battery electrodes, polymeric binders have been shown to play an active role in silicon anodes to alleviate various capacity decay pathways. While the initial focus in binder research was primarily to maintain the electrode morphology, it has been recently shown that polymeric binders can in fact help to stabilize cracked Si microparticles along with the solid-electrolyte-interphase (SEI) layer, thus substantially improving the electrochemical performance. In this review article, we aim to provide an in-depth analysis and molecular-level design principles of polymeric binders for silicon anodes in terms of their chemical structure, superstructure, and supramolecular interactions to achieve good electrochemical performance. We further highlight that supramolecular chemistry offers practical tools to address challenging problems associated with emerging electrode materials in rechargeable batteries.
