ABSTRACT Silicon (Si)‐based materials have emerged as promising alternatives to graphite anodes in lithium‐ion (Li‐ion) batteries due their exceptionally high theoretical capacity. However, practical deployment remains constrained by challenges such significant volume changes during lithiation, poor electrical conductivity, and the instability of solid electrolyte interphase (SEI). This review critically examines recent advancements Si‐based nanostructures enhance stability electrochemical performance. Distinct from prior studies, it highlights application Si commercial domains, including electric vehicles, consumer electronics, renewable energy storage systems, where prolonged cycle life improved power density are crucial. Special emphasis is placed on emerging fabrication techniques, particularly scalable cost‐effective methods electrospinning sol–gel processes, which show promise for industrial adoption. By addressing both technical innovations economic considerations surrounding anodes, this provides a comprehensive roadmap overcoming existing barriers, paving way next‐generation, high‐performance batteries.
