This interesting study analyzes the similarities and differences between battery cells from BYD and Tesla. At a high level it describes the cells this way: > BYD uses a large prismatic cell format, while the Tesla 4680 cell is a large cylindrical cell with a significantly lower volume It looks like the Tesla cells have higher energy density: > Comparing the cells on the cell level, the energy density of the Tesla 4680 cell outperforms that of the BYD Blade cell by margins of 1.5× gravimetrically and 1.8× volumetrically But the BYD cell has better cooling and is more suited to fast charging: > 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.
