摘要:

钠离子层状氧化物是钠离子电池最具潜力的正极材料之一,具有高容量、低成本等优势,因此钠离子电池在大规模静态储能领域有巨大的应用前景。但是,较差的电化学循环稳定性和空气稳定性使其商用化发展受到限制。相比于传统的多晶层状氧化物,单晶层状氧化物具有高机械强度、低比表面积、高压实密度等特点,因此能有效地改善层状氧化物的循环稳定性,提高其综合性能。介绍了钠离子电池层状氧化物的基本结构类型;回顾了目前已经报道的钠离子电池单晶层状氧化正极的合成方法,并分析了各种合成方法的优劣势;阐述了单晶形貌对于钠离子层状氧化物综合性能的提升机理,以及钠离子电池单晶层状氧化物的研究现状,并对未来钠离子电池单晶层状氧化物的发展进行了展望。

Abstract:

As one of the most promising cathode materials for sodium-ion batteries, sodium-ion layered oxide has the advantages of high capacity and low cost, which makes sodium-ion batteries have great application prospects in large-scale static energy storage. However, their commercial development has been limited due to poor electrochemical cycle stability and air stability. Compared with traditional polycrystalline layered oxides, single-crystalline layered oxides are characterized by high mechanical strength, low specific surface, and high taping density, and thus can effectively improve the cycling stability of layered oxides and enhance their comprehensive performance. The basic structure types of layered oxides of sodium-ion batteries are introduced in the paper.The synthesis methods of single-crystal layered oxides of sodium-ion batteries that have been reported so far are also reviewed and the advantages and disadvantages of various synthesis methods are analyzed. Besides, the improvement of single-crystal morphology on comprehensive performance is described and the research status of single-crystal layered oxides in sodium-ion batteries is presented with an outlook of the future development of single-crystal layered oxides for sodium-ion batteries.
