摘要：随着锂离子电池的广泛使用,锂离子电池热安全问题日益突出。相比于成本高、破坏性大的实验方法,建模仿真因其经济、安全、快速等优势成为锂离子电池热安全研究的重要手段。本文从微观建模、单电池建模以及电池组建模三个尺度对最新的锂离子电池模型及其在热安全设计中的应用进行了综述。着重介绍了锂枝晶的生长调控和电解液的安全设计方面的模拟仿真、单电池模型与热方程耦合的应用以及锂离子电池组热模型在优化电池热管理系统方面的研究。最后总结了现有的锂离子电池热模型存在的缺陷,并对锂离子电池热模型未来的研究方法做出了展望。
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.
