The structure of lithium garnets: cation disorder and clustering in a new family of fast Li+ conductors.
The structure of the fast lithium-ion conducting garnets Li5La3M2O12 (M = Ta, Nb) reveals Li+ on both tetrahedral and octahedral sites and suggests that the latter are responsible for the observed Li+ mobility via a clustering mechanism.
