Structural properties of nanostructured lithium manganese oxide as cathode in lithium ion batteries

Lithium manganese oxide, LiMn2O4 is one of the most promising cathode materials for lithium secondary batteries due to its low cost and environmental benign. LiMn2O4 nanorods have been successfully prepared via sol-gel method using citric acid as chelating agent while polycarbonate membrane as the t...
