摘要:

钠离子电池层状过渡金属氧化物正极材料具有价格低廉、比容量相对高的特点,是未来大型储能电站等能源转型设施的重要候选者,与锂离子电池在市场中的应用场景互为补充,为能源转型提供了有力支持,钠离子电池以Na+特有的理化性质而具有极大的开发潜力。然而,层状过渡金属氧化物正极材料在充放电过程伴随着钠离子的嵌入、脱出会产生一系列不利于其电化学性能的变化,如过渡金属溶解、结构相转变、相对较低的能量密度和较差的空气稳定性与循环稳定性,因此对正极材料的结构与性能进行优化变得尤为重要。近10年来许多研究学者针对层状正极材料的失效机制进行了结构上的优化,得到了性能相对良好的正极材料,报道了当前层状过渡金属氧化物正极材料的电化学性能失效机制、改性手段的现状,对钠离子层状氧化物正极材料面临的挑战进行了总结,并对未来发展需要解决的关键问题做出了展望。

Abstract:

Layered transition metal oxide cathode materials for sodium-ion batteries have the characteristics of low price and high specific capacity, which is an important support for energy transition in the future and has great development potential. In the process of charging and discharging, the typical layered oxide cathode materials with the most promising development and application will produce a series of changes affecting their electrochemical properties with the insertion and extration of sodium-ion. Therefore, the modification of cathode materials is particularly important. The current mainstream failure mechanism, modification methods, challenges and key problems to be solved in the future development are summarized and put forward.

Key words: Sodium-ion battery, Layered metal oxides, Cathode materials, Modification methods
