Hi; My son is attending the University of Maryland and knows a professor who has an interest in battery technology. The following link is to a newsletter that discusses GM EV Recall. This newsletter is way over my head. However I believe there are folks who might be interested in the details of this newsletter. Hope this helps in some small way. 😊

"Because a pouch cell package will expand when gas is
generated internally due to cell aging, device manufacturers
need to consider the thickness change when designing a
product. To prevent the battery swelling from destroying the
product in which it is embedded, battery manufacturers
should include the thickness change of the pouch cell over
cell degradation."

Yep, GM (and others) did exactly that.
