“…In Figure 25b, the excellent cycling performance of Si electrode with the mass loading of 1.82 mg cm −2 once again demonstrates the importance of modulating the elasticity and stiffness of the Si binder. Another typical example is that Zhao et al [83] took advantage of the high elasticity of carboxylated acrylonitrile-butadiene rubber to improve the flexible GG binder.…”

While silicon is considered one of the most promising anode materials for the next generation of high‐energy lithium‐ion batteries (LIBs), the industrialization of Si anodes is hampered by the anode's large volume change during the charging and discharging process. In comparison to the traditional graphite anode used in LIBs, the Si anode places more stringent demands on the binder, which must maintain intimate contact between the electrode components and the integrity of the ion and electron transport channels when subjected to frequent large volume changes. The purpose of this review is to cover the recent advances in binder design strategies by examining the molecular structure, chemical functionalities, physical and mechanical properties of the binder materials, as well as the working strategies involved. The challenges in the design of the innovative polymer binder for commercializing Si anodes are discussed, as well as the future development direction and application prospects.

The large volume expansion of a silicon (Si) anode causes severe mechanical failure, limiting its use in lithium-ion batteries (LIBs). Using functional polymers as a binder material is an approach to this issue. We explore the applicability of the water-soluble natural polysaccharide lambda carrageenan (CGN) as a binder for Si nanoparticles in LIBs. The characteristic binder properties of commercial (CGN-com) and custom (ext-CGN) CGNs are investigated. CGN binders exhibit excellent mechanical characteristics, remarkable interfacial adhesion, and strong cohesion. The high density of sulfonyl groups in CGN improves the lithium-ion transport kinetics; CGN effectively buffers the volume expansion of Si during alloying, enhancing cycling and rate performance. After 300 cycles at 0.5 C, the Si@CGN electrode delivers a reversible capacity of 1623.75 mAh g–1 and a rate capability of 2143.72 mAh g–1 at 5 C. The electrochemical performance of Si@CGN-ext is about 91% of that of Si@CGN-com. Under all test conditions, both outperformed Si anodes made with traditional binders. When paired with the commercial NCM811 cathode, full cells using Si@CGN-com and Si@CGN-ext have capacities of 79.96 and 75.68 mAh g–1, respectively, and superior stability for 50 cycles. This study reveals the potential of CGN as a low-cost, sustainable binder for Si anodes.
