Abstract Sodium-ion batteries (SIBs) have emerged as one of the most promising candidates for next-generation energy storage systems because sodium is abundant in nature. The practical application of SIBs critically depends on developing robust electrode materials with high specific capacity and long cycling life, developing suitable anode materials is even more challenging. Alloy-type anodes are attractive for their high gravimetric and volumetric specific capacities, demonstrating great potential for high-energy SIBs, however, huge volume swelling hampered their practical application. Given the encouraging breakthroughs on alloy anodes for SIBs, herein, we present a review of the up-to-date progress and works carried out with alloy-based anode materials for SIBs. We review the synthetic strategies and their detailed electrochemical performance. In particular, we extensively reveal the important roles of alloy-based anodes in the development of SIBs. Research progress of alloy-type anodes and their compounds for sodium storage is summarized. Specific efforts to enhance S.-M. Zheng, C.-Q. Hu, B.

the electrochemical performance of the alloy-based anode materials are discussed. Finally, we proposed multi-component alloys/high-entropy alloys (HEAs) as further research directions for alloy-based anodes. Keywords Alloy-based anodes; High-entropy alloy; Multi-component alloy; Sodium-ion battery
1 Introduction Energy is related to all human beings, it influences our daily life and the global economy. The depletion of fossil fuels and serious environmental problems are urging humans to develop sustainable, low cost and clean energy, such as solar energy and wind energy. However, a crucial problem of clean energy is the discontinuity of energy supply, all these call for a feasible and inexpensive strategy for large-scale energy storage. Given the abundance of element sodium in nature, sodium-ion batteries (SIBs) have emerged as one of the most promising candidates for nextgeneration energy storage systems, especially large-scale energy storage [1–5]. However, the commercialization of SIBs confronts lots of challenges, including inferior cycling stability and low initial Coulomb efficiency, and low energ
