| Abstract: | 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. |
