摘要/Abstract

摘要： Na-Mn-O材料可作为离子交换法制备层状LiMnO2的前体，同时也可以直接作为锂离子电池的正极材料，被认为是锂二次电池研究中很有前景的新型材料。本文重点介绍了Na-Mn-O材料的晶体结构、制备方法，以及以该材料为前体，通过离子交换法合成的LixMnO2正极材料的结构与电化学性能。同时讨论了Na-Mn-O材料在锂二次电池、钠离子电池以及其它一些方面的应用，分析了Na-Mn-O材料作为未来锂二次电池正极材料的发展趋势。

Abstract: The Na–Mn–O materials can be used as a precursor for the synthesis of layered lithium manganese oxides via an ion exchange procedure，or directly be used as the cathode material for lithium ion batteries，which is considered to be a new promising material for secondary lithium batteries. This paper focuses on the structure and preparation methods of the Na-Mn-O material，especially the structure and electrochemical properties of LixMnO2 synthesized by ion exchange method using NaxMnO2 as a precursor. Simultaneously，the application of Na-Mn-O material for the lithium ion batteries，sodium ion batteries and other aspect are also discussed. The development trend of Na-Mn-O as cathode materials for future secondary batteries is analyzed.
