摘要：

Cathode material LiMn2-yCoyO4 spinels were prepared by annealing the mixed precursors, which were synthesized by a low heating solid state coordination method using lithium acetate, manganese acetate, cobalt acetate, and oxalic acid as original materials. The structures and morphologies of the LiMn2-yCoyO4 spinels were investigated as a function of annealing temperature and time. The results showed that all samples in different annealing temperature and time had the same spinel structure. There were some growth and agglomeration in the particles when annealing temperature increased from 450 to 650 degrees C. And the crystal structure was more perfect at the upper temperature. In addition, the electrochemical properties of LiMn2-yCoO4 spinels used as cathode material for lithiurn-ion batteries were studied in detail in this paper. (c) 2005 Elsevier Inc.
