BYD Blade Cell vs Tesla 4680 Cell

This set of graphs provides a comprehensive comparison between the BYD Blade Cell and the Tesla 4680 Cell.

In the pie charts on the left (parts A and B), it is shown that for the BYD Blade Cell, electrode materials account for the largest proportion at 62.02%, with 40.35% being positive active materials and 21.67% negative active materials. For the Tesla 4680 Cell, electrode materials make up 59.91%, with 35.12% positive active materials and 24.79% negative active materials. This indicates differences in the material composition of the two batteries.

The 3D graphs on the right (parts A and B) illustrate the DC resistance of the two cells varying with SOC (State of Charge) and temperature. The BYD Blade Cell shows a certain pattern of resistance change, while the Tesla 4680 Cell has a different trend, suggesting distinct electrical characteristics under different conditions.

In part C, the bar chart reveals that the overall energy density of the Tesla 4680 Cell is relatively higher than that of the BYD Blade Cell in the "Total" item, indicating an advantage of the Tesla 4680 Cell in this regard. Meanwhile, the line graph shows that the Tesla 4680 Cell has a generally higher specific heating value during 1C rate charging and discharging compared to the BYD Blade Cell, and the BYD Blade Cell has a more stable specific heating performance across different SOC levels.

In conclusion, the Tesla 4680 Cell demonstrates relatively higher energy density but also higher heat generation, while the BYD Blade Cell features lower heat generation and more stable thermal performance. These differences in various performance aspects should be comprehensively considered when evaluating the two batteries for practical applications.
