Abstract
Liquid metal batteries (LMBs) are considered as cost-effective energy storage solutions for grid-scale applications. However, magnetohydrodynamic (MHD) instabilities severely prevent the scale-up and commercialization process of LMBs. We verified the reliability of inserting a concentric insulating column into a three-layer liquid metal battery to suppress magnetohydrodynamic instabilities. Additionally, the column must have electrical insulation and magnetic insulation properties. Research indicates that this method can change the distribution of induced magnetic fields inside the battery, thereby reducing internal Lorentz forces. By suppressing internal instabilities, this method enhances charge/discharge efficiency and facilitates the large-scale deployment of individual liquid metal batteries.
