Lithium ion conductivity of lithium hexaoxozirconate Li8ZrO6 doped by Mg2+, Sr2+, Nb5+, V5+, and Ce4+ cations was studied using impedance spectroscopy. The NMR data indicate that in the low-temperature region, lithium ion migration takes place by exchange of Li+ among tetra- and octahedral positions. Data of Raman spectroscopy suggest that the potential reason for the sharp increase of Li8ZrO6 and its solid solutions’ conductivity near 700 K may be melting of LiOH which occurs as a result of interaction between samples and atmospheric moisture.
