<p>This paper focuses on the investigation of tin disulfide (SnS₂) as a promising anode material for sodium-ion batteries (SIBs), which have emerged as a viable alternative to lithium-ion batteries due to the abundance and low cost of sodium. Sodium is widely available, comprising approximately 2.6% of the Earth’s crust, and is also present in large quantities in seawater in the form of sodium chloride, making it a readily accessible and economical resource. As such, sodium-ion batteries are considered a cost-effective energy storage solution that can help mitigate the limitations associated with lithium resource scarcity. Their environmental friendliness and inherent safety—particularly in aqueous systems where electrolytes exhibit high safety—further contribute to their growing appeal. In recent years, both research and industrial development of sodium-ion batteries have accelerated, with technological advancements leading to increasing maturity and broader application prospects. SIBs have demonstrated unique advantages in large-scale energy storage, low-speed electric vehicles, and backup power systems for data centers. This paper provides a comprehensive review of various fabrication methods for SnS₂-based anodes, aiming to offer valuable insights and direction for future research. It concludes with a summary of promising research avenues, serving as a reference for the continued development and optimization of SnS₂ anodes in sodium-ion battery technologies.</p>
