Abstract:

With the widespread use of lithium-ion batteries, the issue of thermal safety of lithium-ion batteries has become increasingly prominent. Compared with the costly and destructive experimental methods, modeling simulation has become an important tool for thermal safety research of Li-ion batteries due to its advantages of economy, safety and speed. In this paper, the latest lithium-ion battery models and their applications in thermal safety design are reviewed in three scales: microscopic modeling, single-cell modeling, and cell pack modeling. The applications of density flooding theory and molecular dynamics simulations in the regulation of lithium dendrite growth and safe design of electrolyte in Li-ion batteries, the application of single-cell modeling coupled with thermal equations, and the study of Li-ion battery group thermal modeling in optimizing the thermal management system of batteries are highlighted. Finally, the defects of the existing thermal models for Li-ion batteries are summarized, and the future research methods for Li-ion battery thermal models are prospected.

Key words: lithium-ion battery, thermal safety, simulation, battery thermal management system
