Advancements in Silicon Anodes for Enhanced Lithium‐Ion Batteries Performance: Innovations Toward Next‐Gen Superbatteries

This is the authors' abstract. We don't add key points for this paper.

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