Structural design strategies of polymer binders for Silicon-based anodes in lithium-ion batteries

Silicon (Si) anodes have emerged as promising candidates for next-generation lithium-ion batteries owing to their high theoretical capacity. However, their practical application is hindered by severe volume expansion and unstable electrode interfaces during cycling. Polymer binders play a critical role in mitigating these issues by maintaining electrode integrity and enhancing interfacial stability. This review provides a systematic classification of polymer binders for Si-based anodes according
