Abstract
Abstract Antimony (Sb) is recognized as a potential electrode material for sodium‐ion batteries (SIBs) due to its huge reserves, affordability, and high theoretical capacity (660 mAh·g −1 ). However, Sb‐based materials experience significant volume expansion during cycling, leading to comminution of the active substance and limiting their practical use in SIBs. Therefore, the volume expansion issue of Sb‐based materials during charging/discharging must be solved to create high‐performance SIBs. This paper presents a detailed review of structural engineering of Sb‐based electrode materials, focusing on the performance effects of different kinds of structures on advanced performance SIBs. Finally, the future development and the challenges of Sb‐based materials are prospected. This paper can provide specific perspectives on the structure construction and optimization of Sb‐based anode materials, so as to promote the rapid development and practical applications of SIBs.
