Published: June 7, 2022

Abstract Hard carbons are promising anode candidates for sodium‐ion batteries due to their excellent Na‐storage performance, abundant resources, and low cost. Despite the recent advances in hard carbons, interpretation of mechanism remains unclear, with discrepancies over a general model describing corresponding structure–property relationship. For rational structural design high‐performance carbon anodes, thorough understanding charge storage relationship between microstructure performance is critical. This review provides comprehensive overview known models describe discussion focused on active sites such as interlayer space, pores, heteroatoms, defects. The present models, including “insertion‐filling”, “adsorption‐filling”, “adsorption‐insertion”, “multistage mechanism” associated analytical characterization, elaborately discussed view challenges prospects unveiling carbons. serves clarify guidance toward anodes batteries.
