液态金属电池（LMB）由两个液态金属电极和夹在它们之间的熔盐离子导体组成。密度比允许三层的稳定分层。 LMB 在 20 世纪 60 年代就已被视为能源转换系统的一部分，最近又重新引起了人们对经济型大规模储能的兴趣。在本文中，我们专注于这种细胞类型的磁流体动力学方面，特别关注电涡流和泰勒不稳定性的可能影响。
Liquid metal batteries (LMBs) consist of two liquid metal electrodes and a molten salt ionic conductor sandwiched between them. The density ratios allow for a stable stratification of the three layers. LMBs were already considered as part of energy conversion systems in the 1960s and have recently received renewed interest for economical large-scale energy storage. In this paper, we concentrate on the magnetohydrodynamic aspects of this cell type with special focus on electro-vortex flows and possible effects of the Tayler instability.
