The development of electric vehicle and plug-in hybrid electric vehicles (EV and PHEV) has increased the demand for fast charging battery technology. The sodium-ion battery has the potential application in the field of low-speed electric vehicle, which puts forward the requirement for the development and application of fast charging technology. However, the slow dynamics of traditional anode materials for sodium-ion batteries limit their application in fast charging conditions. The development of anode materials with fast sodium-ion diffusion ability is the key to achieve fast charging sodium-ion batteries. In this paper, the research status of anode materials for fast charging sodium-ion batteries is reviewed, including the influencing factors for fast charging performance, the structural features and sodium storage mechanisms of different kinds of anode materials, and the strategies to increase the rate performance of anode materials. Finally, the challenges faced by anode materials for fast charging sodium-ion batteries are discussed and the prospect of their future development is put forward.
