“…Also, they provide structural robustness, and depending on their structure, they assist lithium ion conduction [ 12,13 ]. Some examples of the binders used in lithium secondary batteries using liquid electrolytes are polyethylene oxide (PEO), sodium carboxymethyl cellulose styrene butadiene rubber (CMC SBR), sodium alginate (SA), polyvinylpyrrolidone (PVP), carbonyl b cyclodextrin, gelatin, LA132 (a copolymer of acrylonitrile, acrylamide, and acrylic), and ethyl cellulose [ 12,13,14 ]. Among these, the carboxymethyl cellulose or the combination of CMC SBR has proven to be effective to reduce the strain/stress of cathode materials used in lithium secondary batteries because their structure shows a higher chain flexibility to enable favorable dispersibility on the surface of active material [ 13 ].…”

All solid state batteries with cathode composites containing high concentration of active materials are required to achieve higher energy densities. Here, a composite cathode containing up to 89 wt% of high voltage cathode active material (LiNi Mn Co O ) was prepared by covering this with a solution derived solid electrolyte (argyrodite, Li PS Cl) and the incorporation of different content binder (ethyl cellulose). All solid state batteries were fabricated using 80Li S•20P S (mol%) glass and indium metal as a solid electrolyte and anode, respectively. The all solid state battery with a composite cathode containing 0.5 wt% of ethyl cellulose showed an initial discharge capacity of 45 mAhg at 25 °C and maintained 91.7% of the discharge capacity after ten cycles, around 30% higher than that obtained for the battery with the composite cathode without a binder.

“…Overall, the electrode made with CMC/JSR1 = 4/6 shows the best performance, indicating that the optimized ratio of CMC and SBR occurs at around 4/6. It is probably due to that a balance need to be reached between the adhesion force, which is provided by the CMC, and the elasticity, which is provided by the SBR, to improve the reversible capacity of Si containing materials during cycling [17,25] . The peel test results ( Figure 2) show that all the electrodes show strong adhesion force, indicating the combination of CMC and SBR can adhesively bind the Si and graphite materials together in the electrode integrity, which is crucial to improve the cycling stability.…”

“…Therefore, it will be beneficial to develop binders that can be processed with less toxic, or even non-toxic solvents. Recently, it was reported that water-based binder such as styrene-butadiene rubber (SBR) and carboxymethyl cellulose (CMC) effectively improves the cycling stability of silicon electrode [15][16][17][18][19][20][21][22][23][24][25][26] . According to a previous report by Hochgatterer et al [21] , the formation of a covalent chemical bond between the CMC and silicon particle plays an important role in the effective binding and improved performance.…”

“…According to a previous report by Hochgatterer et al [21] , the formation of a covalent chemical bond between the CMC and silicon particle plays an important role in the effective binding and improved performance. Buqa et al [17] and Liu et al [25] found that the capacity retention of Si was significantly improved by using styrene butadiene rubber (SBR) and sodium carboxymethyl cellulose (CMC) as binders. The authors noted that the addition of SBR helps to enhance the elasticity of the laminate since CMC is extremely brittle.…”

Abstract:Cycling reliability is crucial for Si-based materials due to severe volume change during cycles that results in the fast capacity fading. Though the binder only occupies a very low amount of the total mass of anodes, it is proved to perform a key parameter to improve the cycle performance of Si-based anodes. Because they are eco-friendly and cost saving, water-based binders styrene-butadiene rubber (SBR) and carboxymethyl cellulose (CMC) are regarded as the better binder to substitute Poly (vinylidene difluoride) (PVDF) as the binder for Si-based anode. In this study, the anodes are fabricated by simply mixing the active materials (naso Si, graphite and conductive additive) together and using the mixture of SBR and CMC as a binder. The results showed that the retention capacities of the anodes are more than 440 mAh/g after 400 cycles. It indicates that it is an easy and simple way to make high performance anodes.

“…Except for the stable coating layer on the surface of Si [18,39], the electrolyte containing VC with 1 mol/L LiPF 6 in EC/DMC solution has been recognized to favor the formation of stable SEI [34]. Furthermore, sodium alginate, polyacrylic acid and sodium carboxymethylcellulose with carboxyl groups are potential binders for Sibased electrodes compared with the commonly used poly (vinylidene fluoride) for Si-based electrode materials [40][41][42][43]. Particularly, sodium alginate can assist in building a deformable and stable SEI film on the surface of Si, clarifying that it is vital to use a suitable binder to enhance the lithium storage for Si-based anode materials.…”

Silicon-based nanomaterials for lithium-ion batteries

Silicon-based nanomaterials have been of scientific and commercial interest in lithium-ion batteries due to the low cost, low toxicity, and high specific capacity with an order of magnitude beyond that of conventional graphite. The poor capacity retention, caused by pulverization of Si during cycling, triggers researchers and engineers to explore better battery materials. This review summarizes recent work in improving Si-based anode materials via different approaches from diverse Si nanostructures, Si/metal nanocomposites, to Si/C nanocomposites, and also offers perspectives of the Si-based anode materials. Lithium ion batteries (LIBs) as attractive energy storage devices have become ubiquitous power sources for mobile electronics. Increasing power and energy requirements for applications such as electric and hybrid electric vehicles, have spurred intense interest in developing high capacity electrode materials to surpass the capacities of electrode materials used in current LIBs [17]. To achieve the requirements, much research work has been performed on new anode materials with high specific capacities. Silicon has attracted increasing attention as a potential high-capacity anode material because of numerous appealing features such as high theoretical specific capacity of 4212 mAh g -1 , higher safety and stability than graphite (lithiated silicon is more stable in typical electrolytes than lithiated graphite). Si anode materials, however, suffer from some drawbacks involving the drastic volume change (larger than 300%) during the alloying/de-alloying reactions with Li [8], the intrinsic low electrical conductivity, and the unstable solid electrolyte interphase (SEI) formed in the common electrolyte of LiPF 6 . These limitations still challenge the investigation and development on identification of higher capacity for the next generation LIBs. Various advances in Si morphology have been achieved in the past years, demonstrating that nanostructured Si-based materials particularly offer superior properties in LIBs.In this review, we address the recent developments in optimizing Si-based materials via diverse Si nanostructures, Si/metal nanocomposites, and Si/C nanocomposites. In addition, we offer some perspectives for the design of better Si nanomaterials.
