摘要: 本文以18650锂离子电池为研究对象，利用COMSOL Multiphysics仿真软件建立电化学–热耦合模型，并用实验进行论证。从产热角度放电倍率(放电电流)和电极厚度(电池容量)，从散热角度环境温度、散热介质及流动形态对电池热性能进行了仿真分析，全面且系统地比较了各种因素对温度及温差的影响。本文的结果为电池热管理提供了理论基础。
Abstract: The research on the thermal performance of cylindrical cells has been a hot topic in the academic and industrial circles because of its mature manufacturing process, good product consistency but poor cooling capacity. In this study, 18650 lithium-ion battery is selected as the object and an electrochemical-thermal coupling model is established with the software of COMSOL Multiphysics, validating by the experimental data. The thermal performance of the battery was simulated and analyzed from different points of views. It is mainly considered that heat production, concluding the discharge rate (discharge current) and the electrode thickness (battery capacity), and heat dissipation, consisted of the ambient temperature, the medium and the flow pattern. The effects on temperature and temperature difference are compared comprehensively and systematically. Our results provide a theoretical basis for battery thermal management.
