摘　　要：尖晶石LiMn2O4作为锂离子电池最有潜力的正极材料已经成为研究的热点,但其在充放电过程中结构的不稳定制约了其应用。近年来,许多研究学者对LiMn2O4进行稀土掺杂,有效地提高了LiMn2O4材料的电化学性能和循环稳定性。文章综述了近几年在这方面的研究进展。Spinel LiMn2O4 has been studied as the roost promising cathode material in lithium battery. But its structural instability during charging and discharging has limited its application. Recently, many researchers have studied to modity LiMn2O4 by doping raze earths, and improved the electrechemical properties and structural stability of spinel LiMn2O4 effectively. In this paper, recent researches on LiMn2O4 doped raze earths are reviewed.
