To clarify the internal thermal effect of a battery during its charging process, a lithium-ion battery of 27 A·h was taken as the research object. A three-dimensional electrochemical-thermal coupling model of one single battery was established, and the coordinate array mapping method was used to expand the thermal effect of the cell unit to that of the single battery. First, the influence of charging rate on the heat production of the battery was investigated. Then, the detailed heat production in the active layer of negative electrode with different particle radiuses was studied, and the mechanism of influence of particle size on the heat production was analyzed. In addition, the battery temperature distribution with different charging rates under natural convection was also studied. The heating mechanism of lithium-ion battery was elaborated upon, and the overall temperature distribution characteristics of the battery was given, providing a theoretical basis for optimizing the battery structure design and developing the battery thermal management system.

为了研究电池在充电过程中内部的热效应,以27 A·h锂离子电池为研究对象,建立了单体电池的三维电化学-热耦合模型,并采用坐标阵列映射的方法将电芯单元的热效应扩展到单体电池。首先考察了充电倍率对电池产热的影响规律;然后研究了不同颗粒半径下,负极活性层中的详细产热情况,分析了颗粒尺寸对发热量的影响机制;此外还研究了自然对流下,不同充电倍率的电池温度分布情况。通过阐述锂离子电池的发热机理,给出了电池整体温度分布特性,为优化电池结构设计,开发电池热管理系统提供了理论基础。

为了研究电池在充电过程中内部的热效应,以27 A·h锂离子电池为研究对象,建立了单体电池的三维电化学-热耦合模型,并采用坐标阵列映射的方法将电芯单元的热效应扩展到单体电池。首先考察了充电倍率对电池产热的影响规律;然后研究了不同颗粒半径下,负极活性层中的详细产热情况,分析了颗粒尺寸对发热量的影响机制;此外还研究了自然对流下,不同充电倍率的电池温度分布情况。通过阐述锂离子电池的发热机理,给出了电池整体温度分布特性,为优化电池结构设计,开发电池热管理系统提供了理论基础。

锂离子电池  /  电化学-热耦合  /  热效应

To clarify the internal thermal effect of a battery during its charging process, a lithium-ion battery of 27 A·h was taken as the research object. A three-dimensional electrochemical-thermal coupling model of one single battery was established, and the coordinate array mapping method was used to expand the thermal effect of the cell unit to that of the single battery. First, the influence of charging rate on the heat production of the battery was investigated. Then, the detailed heat production in the active layer of negative electrode with different particle radiuses was studied, and the mechanism of influence of particle size on the heat production was analyzed. In addition, the battery temperature distribution with different charging rates under natural convection was also studied. The heating mechanism of lithium-ion battery was elaborated upon, and the overall temperature distribution characteristics of the battery was given, providing a theoretical basis for optimizing the battery structure design and developing the battery thermal management system.
