Electrodes are coated without solvent, skipping the energy-intensive evaporation step that slows production.
Cylindrical cells snap together and use standard welding, unlike pouch cells which need precise stacking and heat sealing.
Tesla's packs bond cells directly into the car's frame, increasing range per pack weight and reducing parts.

Tesla makes electric cars and batteries and is betting on self-driving: camera-only Full Self-Driving software, a Robotaxi service with no safety monitors in several Texas and Florida cities, the two-seat Cybercab, and the Optimus humanoid robot.
