JB has come out and said "no" to this idea. Probably not worth the labor involved in testing and matching cells of similar capacity and resistance.

Or he's leaving for the reasons he stated; spend more time with his family and do what he really loves to do, which is start new businesses.

Ahh makes sense. Didn't realize the system was so sensitive to the cells being matched. To me it is clear they have plans to recycle and it is clear they automate as much as they physically can, so it would make sense that they potentially have come up with a way to break down the cells enough to have it at least make it worth their while if for no other reason then PR. They can say that they will recycle every part of the battery to offset what they need to mine. They also have a few years to figure it out.

Not to nit-pick, but testing the resistance of a cell and putting it in a bucket with other similar cells seems like something a robot could easily and quickly do. But if JB said no then pretty sure that's that. It suggests that they know some better way than to test and reuse the cells.

It's not just testing and sorting but also removing from modules without damaging cells. Cell connections are welded, which would need to be cleanly separated and the surface smoothed and cleaned for re-welding.
Grouping and reuse at the module level might make more sense at some point, especially if cycle life begins to significantly exceed vehicle life.

Buy-the-Dip update:
Company vested shares sold, now need the money to clear, looking like Friday... let the dip continue!
Very small tidbit, the cameras for AP2.0 cost about 25 EUR per piece when bought in volume > 10k. Together with price of the Nvidia shows how big the gap between cost of goods and revenu is on EAP/FSD. In a way misleiding because the biggest 'cost of goods' is likely the development of the software itself, but that's lumped in R&D instead of costs of goods.
I am going. A bunch of us are. We will try to update. Hopefully the "Model 3 viewing" is substantial, but it really might be "Look but don't touch the 2 prototypes everyone knows about". HOPEFULLY it is one of the test fleet and we can see the interior. But if that is the case, they surely would have already shown or leaked it. Wierd if it is the June 2 group tweeting photos and that is how the world learns, but if so we will oblige.

Actually, @FredLambert will almost certainly be there too. So TMC shouldn't have to be hanging on my tweets. But I will promote my handle as we get closer in case it is useful for people.
Also interesting: Will the factory tour show a finished model 3 line. Probably not, and that is fine. Or it will be a line with robots in pretend mode. But 100% of the interest will be in the new line, so the prepared comments by the tour guides will be interesting in itself.

Yeah I'll be there. Though I hear that it is not sure that the Model 3 will be a release candidate, which would be a bummer.

I'll be irritated if they show us the prototype car rather than a Release Candidate
As for Model 3 production, would be great to see the Robotic BodyInWhite Weld line and some of General Assembly line. Not expecting either.

Good to know that you'll cover the reveal event.
Do you think they will show a production vehicle?
BTW thanks a lot for your great work!
Someone showed a snippet of an email that said what would be showed was just the Model 3 that was at the original release. So I wouldn't plan on a RC being there for you to look at.

What a great reveal event, with guests having to sign a NDA
Could as well do a reveal show with PowerPoint slides.
In case TM is not showing lots of real production vehicles or in case there is an NDA for the guests, FUD will be everywhere and I could imagine that the stock will temporarily drop very hard.

Another issue is obsolescence. Say density doubles in ten years. The recoverable minerals in an old battery may produce much more economic value if recycled into a new technology than if simply reused for another decade. It's about making best use of the minerals.
At this point I think JB may be more interested in advancing battery technology than in trying to squeeze the last cycles out of old technology.
