Fig. 2: Local structure of Zr site and formation enthalpy with respect to number of dopant species.

a Local crystal structure of the Zr site with adjacent Li site for the tetragonal phase and b the cubic-phase of garnet. Li1 and Li2 sites for the cubic-phase indicate the 24d tetrahedral and 96h octahedral site, respectively. c Calculated structural parameters of average bond distortion index and bond angle variance between metal and oxygen in the Zr octahedral site as the tetragonal and cubic phase with Li7La3M2O12 composition. d Difference in formation enthalpy energy between the cubic and tetragonal phase with respect to number of dopant species.
