SYNTHESIS AND CYCLING BEHAVIOR OF LiMn2O4 CATHODE MATERIALS PREPARED BY GLYCINE-ASSISTED SOL-GEL METHOD FOR LITHIUM SECONDARY BATTERIES
Spinel-type LiMn2O4 powders having submicron, narrow particle-size distribution and excellent phasepure particles have been synthesized at low temperatures from metal acetate aqueous solution containing glycine as a chelating agent by a sol-gel method. The dependence of the physicochemical properties and cycling characteristics of the spinel LiMn2O4 powders on the various calcination temperatures has been extensively studied. It was found that the physicochemical properties of the LiMn2O4 powders could be controlled by simply varying the calcination temperature. Glycine-assisted LiMn2O4 powders have shown excellent rechargeability and delivered discharge capacity of 119 mAh/g for more than 150th cycles in Li/polymer electrolyte/LiMn2O4 cells.
