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 LiMnPO[subscript 4] to LiFePO[subscript 4]. The barriers for free hole and electron polaron migration in the Mn olivine system are calculated...
