Title: Factors affecting Li mobility in spinel LiMn2O4—A first-principles study by GGA and GGA+U methods

Journal Article · · Journal of Power Sources

The structural changes and voltages of LiMn{sub 2}O{sub 4} spinel as a function of lithium content were investigated with density functional theory (DFT) in the generalized gradient approximation (GGA) and in the GGA with Hubbard U correction (GGA+U). The GGA+U approximation can distinguish the charge separation between Mn{sup 3+} and Mn{sup 4+}, which GGA fails to capture. Therefore with this method the effects of local environments on Li diffusion activation energy barriers in the Li-rich phase could be systematically investigated. Our results showed that the different valences states of Mn ions and their arrangement surrounding the lithium ions have a profound effect on the activation barrier of lithium diffusion in the spinel structure.
