Transport and Electrochemical Properties of Na<sub><i>x</i></sub>Fe<sub>1–<i>y</i></sub>Mn<sub><i>y</i></sub>O<sub>2</sub>‐Cathode Materials for Na‐Ion batteries. Experimental and Theoretical Studies
Abstract

Samples are prepared by solid‐state synthesis and crystallized in P2‐type structure (P6<jats:sub>3</jats:sub>/mmc). Mössbauer spectroscopy studies revealed that in pristine and deintercalated samples the whole iron occurs at a high‐spin Fe<jats:sup>3+</jats:sup> state. Electrochemical impedance spectroscopy measurements exhibited the thermally activated electrical conductivity of Na<jats:sub>0.67</jats:sub>Fe<jats:sub>1–<jats:italic>y</jats:italic> </jats:sub>Mn<jats:sub> <jats:italic>y</jats:italic> </jats:sub>O<jats:sub>2</jats:sub> with relatively high activation energies (≈0.4 eV). Obtained results are supported by the electronic structure calculations (KKR‐CPA method), which indicates that total density of states at the Fermi level increases with manganese content in the sample.
