Comparison of Small Polaron Migration and Phase Separation in Olivine LiMnPO₄ and LiFePO₄ using Hybrid Density Functional Theory
Using hybrid density functional theory based on the Heyd-Scuseria-Ernzerhof (HSE06) functional, we compared polaron migration and phase separation in olivine LiMnPO₄ to LiFePO₄. The barriers for free hole and electron polaron migration in the Mn olivine system are calculated to be 303 and 196 meV, r...
