Perovskites and related oxides are a very important class of functional materials that exhibit a range of stoichiometries and crystal structures. The oxygen diffusion mechanisms and activation energies in these materials are highly influenced by the composition, stoichiometry and crystal structure. We review the significance of a range perovskite related oxides but focus on two characteristic materials: La2NiO4+δ and LnBa2Cu3O7-δ (where Ln = rare-earth cations). La2NiO4+δ is considered as a cathode material for solid-oxide fuel cells, whereas LnBa2Cu3O7-δ is the archetypal superconducting oxides.
