摘要：
Lithium ionic conductivity and spin-lattice relaxation rates were measured in Li2ZrO3 solid electrolytes with different 6Li and 7Li ratios. It is found that single-isotope electrolytes undergo a transition to the superionic state in the temperature range of 430–450 K, accompanied by an abrupt increase in conductivity. As a result of introduction of the other type of the isotope, the conductivity jump disappears in this temperature range. The transition to the superionic state is attributed to the redistribution of lithium ions over energetically nonequivalent lattice sites.
