(2) The conduction in the ab-plane of the material (Figure ) occurs along oct-tet-oct paths, possible in both the Li-as well as the mixed cation layer. The large number of octahedra occupied by the In(III) or Zr(IV) cations blocks conduction in the mixed cation layer, making long range diffusion less probable. In addition, along the c-direction, there is a possible oct-tetoct path, which connects the octahedra in the Li2(2c) octahedra with the tetrahedral Li3(8j) site and the In2/Li4 (4g) site. Due to the high cumulative occupancy of the In2/Li4 site (~0.7), this path is also less probable compared to the oct-tet-oct in the Li-layer, (occupancies ~0.4-0.45), because of the lower probability of having a vacant site to jump to. Specifically, all sites occupied by In can be considered as permanently blocking the conduction along the c-direction.
