| Abstract: | The precursor of Mn0.675Ni0.1625Co0.1625CO3 has been synthesized by a carbonate co-precipitation method, which was used to prepare a high capacity cathode material LiLi0.2Co0.13Ni0.13Mn0.54]O2 for lithium ion batteries. Three kinds of raw materials feeding ways during co-precipitation process were compared. The chemical and physical properties of the precursor and LiLi0.2Mn0.54Ni0.13Co0.13]O2 have been systematically studied. |
