摘要
P2型锰基层状氧化物在开发高能钠离子电池正极材料方面具有潜在的应用前景,但其循环稳定性、倍率性能和表界面稳定性需要进一步提高。针对上述问题,研究人员开发出包括元素掺杂、微观组织结构调控、表面包覆、复合改性等在内的多种改性方法。为此,对这些改性方法的最新研究进展进行综述,将为钠离子电池储能技术的研究和规模化应用提供基础。
P2-type Mn-Based layered oxides show potential applications in developing high-energy cathode materials for sodium-ion batteries(SIBs),while its cycling stability,rate performance,and surface/interface stability need to be further improved.To solve these issues,researchers have developed various modification methods,including element doping,microstructure tuning,surface coating,composite modification,etc.The latest research developments of modification methods for the materials were summarized,which provided theoretical basis and practical guidance for the large-scale energy storage applications of SIBs.
