First Stage of Thermal Aging under Oxidizing Conditions of a Ce0.62Zr0.38O2Mixed Oxide with an Ordered Cationic Sublattice: A Chemical, Nanostructural, and Nanoanalytical Study
A “concerted-densification” based failure mechanism, involving atomic-level changes in both transition-metal cationic sublattice and oxygen/fluorine anionic sublattice, is proposed for the degradation of F-DRX cathode materials.
