Compared with solid metals, liquid metals are considered more promising cathodes for molten slat/oxide electrolysis due to their fascinating advantages, which include strong depolarization effect, strong alloying effect, excellent selective separation, and low operating temperature. In this review, we briefly introduce the properties of the liquid metal cathodes and their selection rules, and then summarize development in liquid metal cathodes for molten salt electrolysis, specifically the extraction of Ti and separation of actinides and rare-earth metals in halide melts. We also review recent attractive progress in the preparation of liquid Ti alloys via molten oxide electrolysis by using liquid metal cathodes. Problems related to high-quality alloy production and large-scale applications are cited, and several research directions to further improve the quality of alloys are also discussed to realize the industrial applications of liquid metal cathodes.

液态金属作为熔融盐/氧化物电解阴极的研究进展

与固态金属相比,液态金属由于其引人入胜的优势而被认为是熔融板条/氧化物电解的更有前景的阴极,包括强的去极化作用,强的合金化作用,出色的选择性分离和较低的工作温度。在这篇综述中,我们简要介绍了液态金属阴极的特性及其选择规则,然后总结了液态金属阴极在熔融盐电解中的发展,特别是Ti的提取以及卤化物熔体中separation系元素和稀土金属的分离。我们还回顾了使用液态金属阴极通过熔融氧化物电解制备液态钛合金的近期有吸引力的进展。列举了与高质量合金生产和大规模应用有关的问题,
