However, to further reduce both the economic and environmental costs associated with LIBs, their performance and lifetime must be further improved. The rapid growth of this industry has been linked to a significant reduction in the cost of lithium-ion batteries (LIBs) over the past decade. The global stock of electric vehicles (EVs) increased from just under 1 million in 2014 to around 7.2 million in 2019, and is forecasted to reach 116 million by 2030. The results are of immediate interest to both cell manufacturers and battery pack designers, while the modelling and parameterization framework created is an essential tool for energy storage system design. On its own, side cooling is more effective than base cooling at removing heat, yet both result in thermal gradients within the cell of a similar magnitude, irrespective of the number of cell tabs. Increasing the number of tabs connecting the jellyroll to the base of the cylindrical-can reduces the internal thermal gradient by up to 25.41%. The validated model is used to study different cell designs and cooling approaches and their effects on the internal temperature of the cell.

The model is comprehensively parameterized and validated with experimental data for 2170 cylindrical cells (LG M50T, NMC811), including direct core temperature measurements. In this work, a comprehensive electro-thermal model is developed for a cylindrical lithium-ion cell. Particularly important for this purpose is the prediction of the internal temperature of cells, because of the positive feedback between heat generation and current distribution. The ability to correctly predict the behavior of lithium ion batteries is critical for safety, performance, cost and lifetime.
