Aditionally, the LFP cells from BYD seem to be more efficient with fast charging, while Tesla’s cells get hot and need much better cooling - emphasis mine.
Comparing this specific heating per volume, the Tesla 4680 cell creates around 2× of the heat to be dissipated at a 1 C load (Figure 8). Thus, when designing a system with the same power requirements, the cooling needed for the Tesla 4680 cells must dissipate approximately 2× more heat per volume than that needed for the BYD cell at the same load. Therefore, the LFP electrode design is more favorable for designing a cooling strategy for fast charging.
Thanks for your remark. It’s easy to misinterpret technical papers like this one from OP.
