Insight into the diffusion mechanism of sodium ion–polaron complexes in orthorhombic P2 layered cathode oxide NaxMnO2

Using the density functional theory, we investigated the geometric, electronic structure, phase stability and electrochemical properties of a potential P2 layer orthorhombic cathode material NaxMnO2 (0 ≤ x ≤ 1) applied for sodium-ion batteries. Herein, we shed the light on the undeniable effect of t...
