Sodium ion battery has the characteristics of rich resource of sodium and low cost, attracting the widespread attention of domestic and foreign researchers, and is considered as the best candidate for replacing lithium ion battery in the field of scale energy storage in the future. In recent years, sodium ion battery research have made significant progress, the research system is continuously enriched. In this paper, the research status of negative electrode materials for sodium ion batteries is reviewed in detail, and the sodium intercalation properties and possible sodium intercalation mechanisms of carbon-based materials, alloy materials, non-metallic elements, metal oxides and organic compounds are mainly introduced. The main problems that these materials are currently facing and possible solutions are discussed. The future research directions and application prospects of sodium ion batteries are also discussed.
