A Novel Compact Thermal Management Model for Temperature Fluctuation Evaluation of Liquid Metal Battery Module

Battery technology, with its dynamic performance and reliability, plays an increasingly vital role in modern largecapacity energy storage infrastructure. Liquid metal batteries (LMB) are one of the most attractive power source candidates for grid energy storage due to their high capacity, low cost and long life. Given the extreme thermal conditions involved, optimizing temperature uniformity and developing effective cooling strategies remain critical challenges in numerous applications. Therefore, a novel compact thermal management model is proposed to investigate the temperature variation and distribution during two different charging/discharging strategies. The results of this study show that adjusting the charging/discharging strategy of the LMB module can suppress the significant temperature fluctuation of the cells during operation.
