Abstract
The present study delves into the roll instability of metal pads within cylindrical liquid metal battery cells, focusing on the characteristics, control, and modeling of the instability within an energetic materials context. Explicit formulas are derived that offer theoretical benchmarks for magnetohydrodynamic solvers OpenFOAM and SFEMaNS, revealing an excellent alignment with experimental observations on gravity wave damping rates in multilayered liquid metal battery systems. Instability thresholds are analyzed for metal pad roll instability, particularly with Mg-Sb liquid metal batteries, and demonstrate effective application for large-scale liquid metal battery cells. Findings highlight the significance of the vertical magnetic field strength, which, even at minimal values, can trigger instability, suggesting implications for both cell design and operational stability within energy storage systems.
