If any can be determined "safe" (including with restrictions that still allow for reasonable use), then they could at least theoretically be used for other purposes like grid storage. Any that cannot be determined "safe" (including with restrictions that still allow for reasonable reuse) will likely be recycled to mine the materials from them.One Big Smoldering Question:
What is happening to the 99.9% of these battery packs which are truly fine.
1. Are the batteries being ground up and poured into waste sites? Recycled?
2. Are the battery packs being repurposed into something else?
3. Are the batteries being resold?
As much as I want a new battery pack and the longer range, the impact of throwing away this much functional power storage and delivery is concerning, no matter the benefit to me as an owner.
The real problem is that LG and GM have not yet found a non-destructive way of determining which packs or modules are "safe" (or "safe" within the usage parameters of a car). If they did have such a method, they could avoid replacing the ones found to be "safe".
