摘要： 钠元素在地壳中储量丰富，价格低廉，并且具有和锂元素类似的物理化学性质，因而钠离子电池被认为是最有希望商业化的新型储能技术之一。然而，钠离子的半径和质量较大，极大地限制了钠离子的迁移和电化学反应，所以发展新型安全稳定储钠电极材料是提升钠离子电池性能和推动其商业化的关键。在众多的电极材料当中，钛基层状材料具有低价、安全和稳定的特点，是近年来钠离子电池的阴极和阳极材料研究的热点之一。因此，本文综述了钛基层状材料在钠离子电池中的研究现状，包括钛基层状材料作为阳极材料、阴极材料和双极材料等方面，并详细探讨和分析该材料所面临的主要科学问题，最后展望钛基层状材料的未来发展趋势。

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.
