Abstract
Liquid metal batteries have attracted much attention in the field of large-scale electrochemical energy storage due to their low cost, high safety and simple structure. The operating temperature of the battery is 300-700 °C. The application of this energy storage technology is inseparable from the efficient thermal management system for battery temperature management and control. The self-generated thermal power of the fully utilized battery will reduce the electrical energy consumed by the thermal management system, thereby improving the energy efficiency of the liquid metal battery energy-storage system. This paper proposes a twodimensional axisymmetric electrochemical thermal model, analyzes the battery's self-generated thermal power characteristics at different charge-discharge rates, and fully considers the multi-physics environment of the battery during operation. By comparing the charge and discharge curves of the battery, the accuracy of the model can be controlled within 0.02.
