a Equiaxed LLZO grain structure; b columnar LLZO grain structure; c analyzed anisotropy factor (\(D_x^{eff}{{{\mathrm{/}}}}D_y^{eff}\)) as a function of temperature for the two grain structures; and d relative diffusivities \({D_x^{\widetilde{eff,co}}}\) and \({D_y^{\widetilde{eff,co}}}\) of the columnar grain structure along the x- and y- directions, respectively, as a function of temperature with respect to the isotropic diffusivity of the equiaxed grain structure. The computed equivalent temperature Te = 273.1 K for this case is indicated in c and d.
