摘要

尖晶石型LiMn₂O₄正极材料具有能量密度高、成本低和无毒等优点,因而被广泛研究。但在循环过程中,尤其是高温下其容量衰减过快,制约了在商业上的应用。简述了Zn掺杂量、温度对LiMn₂O₄结构的影响,重点综述了近15年来单元Zn掺杂以及Zn与不同金属阳离子、阴离子、稀土离子共掺杂对尖晶石型LiMn₂O₄正极材料的电化学性能的影响,展望了Zn元素掺杂在改性尖晶石型LiMn₂O₄正极材料方面的发展前景。

Abstract

The spinel-type LiMn₂O₄ anode material has been widely studied for its high energy density,low cost and non-toxicity.However,its commercial application is restricted during the cycle,especially its capacity decreases too fast at high temperatures.The influence of Zn doping amount and temperature on the structure of LiMn₂O₄ were briefly described.The effects of unit Zn doping and Zn co-doping with different metal cations,anions and rare earth ions for the past fifteen years on the electrochemical performance of spinel LiMn₂O₄ anode materials were reviewed.The development of Zndoped LiMn₂O₄ was prospected.
