Multi-physics Coupled Simulation and Model App Development for Lithium Slurry Batteries

Abstract

Abstract Lithium slurry batteries, as an electrochemical energy storage technology, have the advantages of high operating voltage, large energy density and flexible configuration, and have broad application prospects. Due to the high cost of experiment time, materials traditional experimental methods have low R&D efficiency and the internal reactions and physical fields of batteries are very complex, research on battery performance is difficult and the threshold is high. To overcome this challenge, A new dynamic three-dimensional multi physical field coupling model for lithium slurry flow batteries has been proposed. This model can study the fluid dynamics of slurry batteries, the electrochemistry of lithium electrode reactions, the transport of lithium in solid particles, and the mass balance in storage tanks. Based on this model, we develop model applications using Comsol’s built-in interface. This app has a simple interface and simple operation to reduce the threshold for researchers and improve their research efficiency.
