| 中文摘要 | Structural and dynamic properties of spinel LiMn2O4 are investigated firstly from ab initio molecular-dynamics (MD) calculations. This method included all the interactions among the ions so that, more reliable results have been obtained comparing with the conventional classical MD simulations. Full MD simulations are performed to study the structural and diffusive properties while selective MD simulations are performed to study the migration energy barrier of Li ions. Results indicate that Li ions tend to take one fcc sub-lattice in the Li0.5Mn2O4 crystal. The migration energy barriers of Li ions from one 8a site to another nearest-neighbor 8a site are about 0.23 and 0.61 eV for LiMn2O4 and Li0.5Mn2O4, respectively. |
