Preparation and characterization of LiMn2O4 nanorod by low heating solid state coordination method

Cathode material LiMn2O4 nanorod was prepared by annealing of the mixed precursor which was synthesized by low heating solid state coordination method using lithium acetate, manganese acetate and oxalic acid as starting materials. The structures and morphologies of the LiMn2O4 nanorod were investigated as a function of annealing temperature and time. The results showed that all samples in different annealing temperatures and time have the same spinel structure. The higher the annealing temperature is, the more complete the crystal structure forms, and the larger the particle size is. In addition, the electrochemical properties of the LiMn2O4nanorod were studied in this paper.
