“…The strong polar property of alginate can also increase the interfacial interactions among the Si particles, the current collector, and the binder. Since then, a large number of alginate-based binders have been investigated, such as alginate hydrogel [77,78] and crosslinked alginate, [79][80][81][82][83] and prolonged calendar life for Si electrode was achieved to varying degrees. The binding force of alginate hydrogel is strongly dependent on the metal ions introduced, the Ba-Alg exhibits a higher peeling force of 2.656 N over the other M-Alg (M = Zn, Mn, Al, Ba, Ca, Na).…”

Polymer binders as a critical component in rechargeable batteries provide the electrodes with interconnected structures and mechanical strength to maintain the electronic/ionic transfer during battery cycling. The conventional binders, such as polyvinylidene fluoride (PVDF), are not ideal candidates due to their relatively low adhesiveness, weak mechanical strength, and poor functionality for high‐energy‐density batteries with a thick electrode and/or a high‐capacity electrode. Nevertheless, the binder has not yet received the attention that reflects its importance in batteries. The requirements of high energy density batteries make essential the exploration of advanced polymeric binders, which possess particular functions. In this review, state‐of‐the‐art binder design strategies are sorted in terms of the challenges of various electrodes (anodes and cathodes for lithium ion batteries (LIBs) and sulfur cathodes for Li–S batteries), which have been commercialized or have the potential for practical cells. A deep insight into how the polymeric binders improve the cell performance and the design principle of new binders is also provided. Finally, a perspective on the direction of future binder development for high‐energy‐density batteries with long cycle life is presented.

“…Aside from the problems directly related to the silicon itself, developing a strong polymer binder that can endure large volume changes of Si and prevent electrodes from rupturing has also been widely pursued recently. Polymers such as poly(acrylic acid) (PAA) that consist of many carboxylic acid functional groups 18 , 19 and polysaccharides such as alginates 20 , 21 , Xanthan gum 22 and Pullulan 23 have been shown—due to their excellent physical properties resulting from their strong interactions with OH groups on silicon particles—to be of use for increasing the lifespan of Si anodes. These polymers may thus be good candidates as polymeric binders for Si as well as other high-capacity anode materials such as Sn and Ge, and may even be a viable substitute for carboxymethyl cellulose (CMC)/styrene butadiene rubber (SBR), the binder currently used in commercial graphite anodes.…”

Graphite is used commercially as the active material in lithium ion batteries, frequently as part of a graphite/SiOx composite. Graphite is used in conjunction with SiOx to overcome the limited energy density of graphite, and to lessen the adverse effects of volume expansion of Si. However, electrodes based on graphite/SiOx composites can be made with only 3–5 wt % SiOx because of the increased failure of electrodes with higher SiOx contents. Here, we developed a new polymer binder, by combining dopamine-grafted heparin with the commercial binder carboxymethyl cellulose (CMC)/styrene butadiene rubber (SBR), in order to more effectively hold the SiOx particles together and prevent disintegration of the electrode during charging and discharging. The crosslinking using acid-base interactions between heparin and CMC and the ion-conducting sulfonate group in heparin, together with the strong adhesion properties of dopamine, yielded better physical properties for the dopamine-heparin-containing CMC/SBR-based electrodes than for the commercial CMC/SBR-based electrodes, and hence yielded excellent cell performance with a retention of 73.5% of the original capacity, a Coulombic efficiency of 99.7% at 150 cycles, and a high capacity of 200 mAh g−1 even at 20 C. Furthermore, a full cell test using the proposed electrode material showed stable cell performance with 89% retention at the 150th cycle.

In the area of novel power sources, silicon anode in lithium-ion battery, with an ultrahigh theoretical specific capacity of 4200 mAh•g-1 , has drawn numerous attentions and got to highlighting spot. Nevertheless, it suffers rapid capacity loss and short cyclability ascribed to the huge volume change during lithiation/delithiation process. So far, one of the most effective methods to ameliorate performances of silicon anode is to modify binders. In this way, the contact integrity among active materials, conductive additives and current collectors can be maintained, which may weaken the cracking and pulverization, keep high specific capacity as well as strengthen the cyclability of silicon anode. Considering both the advantages of silicon anode and the developments of binders, a review on silicon anode in lithium-ion battery will be demonstrated systematically. Besides, we describe the main effects of binders against battery performances. We hope that our review would provide research directions in the developments and applications of binders used in silicon anode of lithium-ion battery.
