“In the new design, by contrast, the battery cells themselves will be the structural support. "It effectively glues the cells to the top and bottom sheet" using a "structural adhesive," Musk said.”
Sounds like a challenge for repairability.
Also, do the irreplaceable batteries in iPhones and MacBooks provide structural support, too?
I like the way that Ars headlines the exciting claims, but also includes the boring facts. For example, that these claims would represent basically industry standard progress on price/kwh, and that 3 years from Elon Musk is not a useful claim, and that Tesla is stating several mutually exclusive claims.
