This quote shows once again Elon and Tesla are focused on the problems that matter.
My guess is this is as hard as landing a rocket on a drone ship.
I posted some videos in the Battery Day thread, my impressions where:-
- LiOH is needed for high nickel batteries
- One known source of LiOH comes from hard rock mined in Australia and processed in China.
- Lithium Carbonate (Li2CO3) seems to be easier to make with multiple sources.
- I'm not sure if there is more than one source of LiOH.
- Mining in the US and shipping to China for processing doesn't make a lot of sense.
Tesla may or may not say something about this at Battery Day, but my hunch is they might have a quiet R&D project going, this is a hard problem, but an important problem, the kind of problem they usually take on.
If they are doing R&D this is possibly a 5-7 year project, I doubt they will be demonstrating anything in this area at Battery Day.
