A key challenge in lithium-ion battery research is the need for more transparency regarding the cell design and production processes of battery as well as vehicle manufacturers. This study comprehensively benchmarks a prismatic hardcase LFP cell that was dismounted from a state-of-the-art Tesla Model 3 (Standard Range).
Because the Biot numbers linearly increase with the film thickness, the film resistance gains in importance at higher film thicknesses. For this reason, it has to be verified whether the transport resistances within the porous structure of a lithium-ion battery electrode can be neglected for higher electrode thicknesses as well.
Conclusion This study addressed the lack of transparency in the design and production of automotive-grade lithium-ion cells by comprehensively investigating a 161.5 Ah prismatic flat wound hardcase cell from a state-of-the-art Tesla Model 3. The cell was disassembled to the material level to trace process steps and manufacturing peculiarities.
High energy density provides Li-ion batteries a high capacity what derives in a long autonomy, that reduces or enlarges with power requirements, as the battery capacity is affected by discharge rate [ , , , , , ].
All values are averaged values of the film properties of the experiments, which were repeated at least three times. The films themselves deviate in their film thickness, with a growing standard deviation with increasing area weight, which lies between 6 and 8% of the average film thickness.
