Magnesium ion mobility in post-spinels accessible at ambient pressure

Hannahn D. C., Gautam G. S., Canepa P., Rong Z. and Ceder G.; Chem. Commun 53, 5171-5174 (2017).


We propose that Ti-containing post-spinels may offer a practically-accessible route to fast multivalent ion diffusion in close-packed oxide lattices, with the caveat that substantial thermodynamic driving forces for conversion reactions exist.
