Yes. Like I said before he said they are able to make them but they are not getting the yield (% passing QC tests). So if they are making some good ones, they could put them in some low rate production cars like the Plaid Model S or Roadster. Better not to waste them.
Remember when OLED TVs were so expensive? They were also low yield until they refined their production process. The good ones were OK just more expensive to produce because of the bad ones. As they have made the process better and improved their yield, they have become less expensive and more plentiful.

Apparently, Tesla has made some additional moves to obtain Lithium supplies in the near-term, before their "Nevada Lithium Clay" project is ready.

https://www.benchmarkminerals.com/m...s-foundations-of-china-dominated-spodumene-2/

Some highlights:

Piedmont Lithium – a lithium developer aiming to produce spodumene from North Carolina – today, announced an off-take with Tesla for “approximately a third” of its 160,000 tpa spodumene output each year for a five year period.​
Tesla will use a hydrometallurgical process to turn its spodumene concentrate into lithium hydroxide, eliminating the use of sulphuric acid. However, this process has not yet been built at commercial scale so will provide an additional hurdle for Tesla.​
...confusion reigned over Tesla’s lithium direction in particular the EV maker's plans to extract lithium from Nevada-clay, which Benchmark understands is more of an early stage idea than a supply solution. Tesla’s foray into lithium chemical production is a clear indication that the EV and battery cell maker favors the spodumene route for near term lithium supply.​

Tesla continues to move further up the supply chain. :)

I'm surprised by the number and complexity of coolant connections, but this no doubt a prototype with more revisions on the way

I wonder if those are 4680 sized holes.

They are indeed. A structural pack implies using 4680 factor cells, it's the future pack design going forward for all new car models. Model Ys made in Berlin will be the first existing car design to use it however.

Interesting how the coolant delivery appears to be multithreaded - probably necessary for optimal battery management. But yeah, so many hose connections. Let’s see what Sandy Munro has to say.

Given they're not doing modules anymore they need to find a more efficient method of evenly distributing the coolant so doing it from the sides with multiple loops is the way to go.
