与现有技术相比,本发明具有以下有益效果:
(1)针对现有钠离子电池三元正极材料通常含锰,存在Jahn-Teller效应引起的结构坍塌等问题,针对该问题,本发明开发了一种新的正极材料NaNixCoyZr1-x-yO2来克服该缺陷,且该正极材料的性能相对较好,然而,申请人发现,该正极材料虽然能够克服该技术问题,但是仍存在稳定性和克容量相对较低,循环性能相对较差。本发明提供一种采用铌进行包覆和掺杂双重改性的三元正极材料,该材料表面形成NaNbO3包覆层,获得了一种一致性好、离子电导率较高、高容量、循环性能好的钠离子电池三元正极材料。
(2)本发明开发了正极材料NaNixCoyZr1-x-yO2消除了Jahn-Teller效应,并通过Nb对该正极材料基体进行改性来获得一种一致性好、离子电导率较高、高容量、循环性能好的钠离子电池三元正极材料。本发明采用高能球磨将前驱体、钠源和铌源混合均匀,并在高能球磨时添加特殊添加剂及有机溶剂,能改善前驱体颗粒的形貌,将共沉淀时附着与颗粒表面的反应不完全的物质通过高能球磨与颗粒分离,且可以有效防止前驱体二次颗粒的破碎,使钠源、铌源、添加剂均匀分散在颗粒表面;最后通过过筛将细小颗粒过滤,可以提高颗粒粒径分布的集中度,进而在烧结过程中减少结块,这种方法操作简单、在改善钠离子电池正极材料形貌的同时,提高了材料的结构稳定性。铌掺杂进入TM层,由于铌的原子半径较大,扩大了晶格间距,起到了支撑材料金属层的作用,稳定了晶格结构,同时有利于钠离子的传输。另外铌的包覆层可以有效减少电极材料与电解液副反应的发生,同时铌酸钠的离子导率较高,提供钠离子的三维快速传输通道,可以增加钠离子传输速率及材料循环稳定性能。该材料具有良好的倍率性能和优异的循环稳定性,且制备方法简单可控。
(3)本发明的制备方法工艺简单、简化了制备过程,成本低廉、适合工业化生产,且对正极材料的电化学性能有明显的的改善。
