摘要:

由于地球钠元素资源丰富、来源广泛,钠离子电池被认为是将来能够替代锂离子电池用于大规模储能的新型二次电池技术之一。正极材料作为钠离子电池的重要组成部分,决定了钠离子电池电化学性能的优劣。然而由于钠离子半径较大,开发结构稳定且具有快速钠离子扩散性能的正极材料是获得高性能钠离子电池的挑战之一。近年来,越来越多的层状正极材料体系被开发出来,并展现出良好的电化学性能,对于钠离子电池具有较好的应用前景。本文综述了目前常见的层状钠离子电池正极材料,重点分析和探讨了层状钠离子电池正极材料的储钠机制,并展望了未来钠离子电池正极材料的发展趋势及应用前景。

Abstract:

Na-ion batteries are regarded as a potential new rechargeable battery technology to replace lithium-ion batteries for large-scale energy storage applications in the future due to the rich abundance of Na sources and their low cost. Cathode materials, an important component of Na-ion batteries, determine the electrochemical performance of Na-ion batteries. Due to the large ionic radius of Na+ ions, developing cathode materials with stable structures and fast Na+ ion diffusion is still a significant challenge. Recently, many layered materials have been explored as cathodes with promising electrochemical performances, exhibiting great potential for application in Na-ion batteries. In this review, recently reported layered cathode materials are summarized and their Na storage mechanisms are carefully analyzed and discussed. Finally, perspectives on the future development of layered cathodes and their potential applications in Na-ion batteries are provided.

Key words: sodium-ion batteries, cathode material, layered transition metal oxides, Mn-based systems
