Rechargeable lithium-ion batteries (LIBs) have attracted great attention due to their large-scale energy storage applications such as electric vehicles (EVs) and grid-scale energy storage systems (ESSs). The ongoing transi tion towards EVs has accelerated ever-increasing demand for LIBs that causes the shortage of lithium metal resources and their expensive price. Therefore, great efforts have been made to exploit an alternative system that replaces the conventional LIBs. While sodium-ion batteries (SIBs) can be the most evident alternatives to LIBs based on the natural abundance and low cost of sodium resources, the major scientific challenges reside in developing the new anode materials due to the poor performance of conventional LIB anodes in Na cells, such as graphite and silicon. This arti cle reviews the potential of SIBs as promising alternatives to LIBs and recent progress in developing high-performance anode materials for SIBs. The strengths and drawbacks of recently developed anode materials have been discussed, including graphite, hard carbon, silicon, phosphorus, and other transition metal compounds such as oxides, phosphides, and sulfides.
