The automaker claimed a potential to reduce battery cost by over 50% with the new design; it has been trying to bring it to volume production since, but it has run into some bottlenecks.
In a conference call following the release of its Q1 2023 financial results, Tesla gave a detailed update about its 4680 battery cell production.
Drew Baglino, Tesla’s senior VP of engineering, said about the 4680 cell:
On Battery Day, we established a cost-down roadmap through 2026 across five areas of effort. There was the cell design we discussed; anode and cathode materials, the structural pack concept, and the cell factory itself. We’ve been making progress across all these aspects since then. For the Cell Factory, for the Texas 4680 factory, we are part way through building and commissioning and installing and operating, will be 70% lower capex per gigawatt hour than typical cell factories when fully ramped in line with what we described on Battery Day. And we’re continuing to further pursue densification and investment reduction opportunities in future factory buildouts like in Nevada.
Tesla is producing 4680 cells at its pilot plant in Fremont, but it is expected to reach higher volume production at Gigafactory Texas, which is the “cell factory” Baglino is talking about here.
