| 钠离子电池因其成本低、安全性高、来源丰富、低温性能优良等优点，有望在未来成为锂离子电池的强有力替代品。在钠离子电池体系中，正极材料是影响电池性能的一个重要因素，也得到了研究者们的广泛研究。众多钠离子电池正极材料中，层状氧化物材料凭借能量密度高、倍率性能好等优势，被认为是最具潜力的正极材料，也成为了研究热点。然而，层状氧化物材料存在着在充放电过程中的不可逆相变及在空气中的稳定性较差等问题，制约了其在工业上的应用发展，因此，亟需对层状氧化物正极材料的结构与性能进行优化。本文概述了优化层状氧化物正极材料的结构与性能的方法，包括元素掺杂、表面改性、制备复合相结构及一些其他的策略，并对层状氧化物正极材料在钠离子电池中的应用进行了美好展望。 |
| 英文摘要: |
| Sodium-ion batteries are expected to become a strong substitute for lithium-ion batteries in the future because of their low cost, high safety, abundant sources and excellent low-temperature performance. In the sodium-ion battery system, the cathode material is an important factor affecting the battery performance, and has been widely studied by researchers. Among the cathode materials of sodium-ion batteries, layered oxide materials are considered as the most potential cathode materials by virtue of their high energy density and good magnification performance, and have also become a research hotspot. However, the problems such as irreversible phase transition in charge and discharge process and poor stability in air restrict the development of the application of layered oxide materials in industry. Therefore, it is urgent to optimize the structure and properties of layered oxide anode materials. In this paper, the methods of optimizing the structure and properties of layered oxide cathode materials, including element doping, surface modification, preparation of composite phase structure and some other strategies, are summarized. The application of layered oxide cathode materials in sodium ion batteries is prospected. |
