One such interesting factor to understand is anisotropy of the diffusion or in its extreme case reduced dimensionality, which may arise for certain crystal structures. While one dimensional diffusion is typically not favourable for long-range ion conduction, two-dimensional conductors need favourable microstructure for good percolation . Examples for anisotropy in layered (Li-)ion conducting materials are manifold, as for example graphite , LiCoO2 10 , LiFePO4 11 , TiO2-B , Li in hexagonal TiS2 , hectorite-type silicate and β-alumina . Considering that crystallites of solid electrolytes like the monoclinic Li3InCl6, which has a layered atomic arrangement, may grow into platelets and may have anisotropic properties, this could very well impact the efficacy of ionic transport in composites.
