The temperature distribution of a LiFePO4 battery was studied by using the finite difference method in this study. The heat generation considers both Bernardi expression and current heat generation in current collectors. A temperature measurement experiment at the geometry center inside battery at 2C discharge was done to validate the model temperature prediction results. The effects of electrode configuration such as placing and center distance of current collecting tabs on battery temperature distribution were analysed. The results showed that the placing and center distance of current collecting tabs have significant effects on temperature rising and uniformity. The results could contribute to the battery design.
