Conseguentiy, it has been one of the important appiied fiieds. The deveiopment importance of iithium ion battery technoiogy is described. Ef- fects of rare earth doped on structure and eiectrochemicai performance of positive eiectrode materiais for iithium ion batteries are summarized. The research progress in rare earth-doped positive eiectrode materiais of spinei iithium manganese oxide for iithium ion batteries is introduced in detaii. The appiication deveiopment prospect of rare earth doped in positive materiais of iithium ion battery is viewed. As the further study of rare earth-doped which promotes the progress of high performance iithium ion batteries, it wiii be an important fieid for the deveiopment of high specific capacity batteries in the future research.
