A novel intercalation cathode material for sodium-based batteries

"A novel intercalation cathode material for sodium-based batteries", B. Rousseau, V. Timoshevskii, N. Mousseau, M. Côté, and K. Zaghib, Electrochemistry Communications 52, 9 (2015).

We propose NaFeZr₂F₁₁ and NaFeTi₂F₁₁ as novel materials for Na intercalation cathodes. The average sodium intercalation voltage for these compounds is about 4.0 V from first principles computations. The origin of this large voltage for a nominal Fe²⁺/Fe³⁺ redox couple is proposed to be a combination of the fluorine “booster” effect, the inductive effect and the stiffness of the proposed structure upon desodiation.
