摘要
三元正极材料LiNi_(0.5)Co_(0.2)Mn_(0.3)O_2具有能量密度大、比容量高、成本低等优点,已基本实现产业化。但该材料的容量保持率低和热稳定性能差阻碍了其全面快速的发展。综述了制备工艺的优化、掺杂和包覆等改性方法对三元正极材料性能的影响,重点介绍了热电化学和数值模拟的研究现状和应用。
LiNi0.5Co0.2Mn0.3O2cathode material with enormous energy density,higher capacity and lower cost has basically realized industrialization.But its comprehensive and rapid development are hampered attributed to its low retention rate and poor thermal stability.In this paper,the effects of preparation process optimization,doping and coating methods on the properties of ternary cathode materials are reviewed.The research status and application of thermoelectrochemistry and numerical simulation are introduced.
