Synthesis and Characterization of Nano Crystalline LiMn2O4 Powder for Lithium-Ion Batteries

A simple solid state combustion method has been tried for the preparation of nano particle sized LiMn2O4 powder with urea as the igniter and glycerol as the binding material. Nitrates of Li+and Mn3+ were mixed together to form a homogeneous paste. This paste was carefully heated to 100o C in the muffle furnace and then the product is heated to 800oC for 12 hrs. The obtained nano powder was subjected to XRD, TEM, and FTIR analysis. The particle size of the material was roughly calculated from the X-ray data using Scherrer equation. The TEM analysis was carried out in detail to confirm the particle size. The procedure is very simple and novel.
