Abstract: Rechargeable sodium-ion batteries have been considered as one of the most promising energy storage technologies, owing to the low cost and natural abundance of sodium in the earth's crust. However, the issues of the large radius and heavy weight of sodium ion limit the migration and reaction of sodium ion during charging and discharging processes. Therefore, development of novel electrode materials with stability and safety is essential for commercialization of sodium-ion batteries. Among the many electrode candidates for sodium-ion batteries, titanium-based layered materials have recently attracted great interest due to their low cost, stability and safety. This paper summarized recent research progress on titanium-based layered materials for sodium-ion batteries, including titanium-based layered anodes, cathodes, and bipolar electrodes. We provided a detailed analysis and discussion of the scientific issues of titanium-based compounds for the sodium storage. Moreover, the future developing trend of sodium-ion batteries were also briefly introduced in this review.

Key words: sodium-ion batteries, layered materials, anode materials, cathode materials, bipolar materials
