Abstract We examined the electronic property of Sb-doped Na0.785CoO2 using density functional calculations based on GGA+U formalism. We demonstrated that Sb dopants were the most stable when replacing Co ions within the complex Na0.875CoO2 lattice st

Identifying high-voltage cathode materials is critically important for increasing the energy density of Na ion batteries. Through a comprehensive density-functional survey, we demonstrate that oxygen redox in $R\overline{3}$ (ilmenite structure) $\ma

Through comprehensive density functional calculations, we demonstrate oxygen's significant participation in the redox reaction in a Na excess NaxRuO3 cathode material. The availability of O electrons for the redox reaction originates from the local c

We theoretically investigated the electronic, electrochemical and magnetic properties of Sb doped NaxCoO2 (x = 1, 0.75 and 0.50). SbCo dopants adopt 5+ oxidation state in NaxCoO2 host lattice for all Na concentrations (x). Due to high oxidation state

The effect of Ru doping on the magnetic coupling among Co ions and on the Seebeck effect in Na0.5CoO2 was systematically studied using density functional theory. It was found that the Ru dopant takes the 4+ oxidation state and replaces a Co4+ ion. In

$Na_xCoO_2$ that comprises of alternating Na and $CoO_2$ layers has exotic magnetic and thermoelectric properties that could favorably be manipulated by adding dopants or varying Na concentration. In this work, we investigated the structural and elec
