Abstract

In order to get homogeneous partially substituted lithium manganese oxide positive electrode material, we applied carbonate co-precipitation method to the synthesis of multi-doped Li1+xMyMn2−x−yO4(M = Co, Ni) spinel compounds. X-ray diffraction experiment and B.E.T measurement revealed that the Li1+xMyMn2−x−yO4(M = Co, Ni) spinel compounds having small surface area (0.16-0.22 m2 g−1) were successfully synthesized using carbonate co-precipitation method. The spinel compounds showed good capacity retention upon cycling test at an elevated temperature, and it was remarkably increased with increasing lithium doping amount. Furthermore, we found that rate capability of spinel compounds also depend on lithium doping amount.
