Ionic selectivity is of significant importance in both fundamental science and practical applications. For instance, an ion-selective material allows the passage of a particular kind of ions while blocking the others, which could be used for purification of materials. Herein, the Li-ion-selectivity of a garnet-type solid electrolyte is discussed by comparing the difference of activation energy between different ions migrating in solids. The high ion-selectivity is confirmed by harvesting high-purity metallic lithium (99.98 wt%) from low-lithium-purity sources (80 wt%) at a moderate temperature (190 °C). This gives it huge potential in separating lithium with impurities especially alkali and alkali-earth elements. The cost of metallic lithium production is only 25% of the international lithium price. The proposed electrochemical metallic lithium separating method is advantageous compared with the traditional process in terms of efficiency, safety, and cost.

石榴石固体电解质的高离子选择性能够分离金属锂
离子选择性在基础科学和实际应用中都具有重要意义。例如,离子选择性材料允许特定种类的离子通过,同时阻止其他离子,这可用于材料的纯化。本文通过比较固体中迁移的不同离子之间的活化能差异来讨论石榴石型固体电解质的锂离子选择性。通过在中等温度 (190 °C) 下从低锂纯度源 (80 wt%) 中收获高纯度金属锂 (99.98 wt%) 证实了高离子选择性。这使得它在分离锂与杂质尤其是碱金属和碱土元素方面具有巨大的潜力。金属锂生产成本仅为国际锂价的25%。所提出的电化学金属锂分离方法与传统工艺相比在效率、安全性和成本方面具有优势。
