Contrasting a BYD Blade prismatic cell and Tesla 4680 cylindrical cell with a teardown analysis of design and performance
Highlights
- Design, materials, performance, and process flow of BYD Blade and Tesla 4680 cell are compared
- Tesla uses laser welding; BYD combines laser and ultrasonic for electrode connections
- Tesla 4680 cell generates 2× the heat per volume of BYD Blade at a 1 C specific load
- PAA and PEO binders identified in Tesla 4680 anode warrant further investigation
