Battery Day Discusses 4680 Cells
Battery Day on September 22, 2021 revealed 4680 battery technology critical to the Cybertruck
During Tesla’s Battery Day event on September 22, 2021, the company discussed battery technologies and manufacturing innovations that would be relevant to the Cybertruck. The event highlighted Tesla’s efforts to reduce battery costs and improve energy density, which would be critical for the truck’s range and performance. The Cybertruck’s battery requirements were discussed as a key challenge, with the vehicle needing to balance range, payload capacity, and towing performance.
Tesla’s new 4680 battery cells were a centerpiece of the event, with detailed explanations of the tableless electrode design and dry coating process. The cells offered higher energy density and lower manufacturing costs compared to the previous generation, but they were still in early production. The Battery Day event also showcased Tesla’s progress on structural battery packs, which could be adapted for the Cybertruck’s unique chassis design.
