Abstract

The spinel LiTi<sub>2</sub>O<sub>4</sub> system is of interest in battery applications and used as an anode material... Molecular dynamics calculations were carried out to investigate the effects of temperature on spinel lithium titanate. The NVE ensemble was used, whereas the temperature was varied, ranging from 300K-3000K. The radial distribution functions, diffusion coefficient and x-ray diffractions were analysed. It was observed that the LiTi<sub>2</sub>O<sub>4</sub> system undergoes structural transformation from spinel to ramsdellite at 1148.15K, which gives a good agreement with experimental data acquired.
