Abstract Due to the high theoretical lithium storage capacity and moderate voltage platform, silicon is expected to substitute graphite and serves as the most promising anode material for lithium‐ion batteries (LIBs). However, substantial volume change during cycling subjects the silicon anode to electrode pulverization and conductive network damage, extensively limiting its commercial purpose. Strategies, such as alloying, nano‐crystallization, and compositing, are developed against these problems. This review introduces the attractive alloying modification method and summarizes the recent advances in microstructure‐engineered silicon alloy anodes for LIBs. The electrochemical performances of silicon alloy anodes with various morphologies, such as nanoparticles, nanowires, two‐dimensional layered structures, porous structures, and thin films, are discussed in detail. The challenges for the commercial application of silicon alloy anodes are elaborated in the end. This review provides a comprehensive overview and concerns of microstructure‐engineered silicon alloy anodes for potential applications in LIBs.
