基于电化学-热耦合模型，模拟了常温条件下 LiFePO4 /Graphite 锂离子电池的放电过程，并对电池内部正负电极各个位置的电化学反应速度演化规律进行了模拟计算研究。结果表明：放电过程中电极各处的反应速率不同，且是动态变化的。

Electrochemical Thermal Model Based Research for Electrochemical Performance of Lithium Ion Batteries Jia Ming, Tang Yiwei, Cheng Yun, Du Shuanglong, Li Jie (School of Metallurgy and Environment, Central South University, Changsha City, 410083, China) Abstract: An electrochemical-thermal coupling model for lithium ion batteries was developed to investigate the discharge process of a LiFePO4 /Graphite battery. The variation of electrochemical reaction rate at different sites of positive or negative electrode was studied. The simulated results showed that the electrochemical reaction rate within the cell was changing with the location and time. Keywords: Lithium ion battery, Electrochemical behavior, Modeling
