There is something in the MXWL acquisition that might be a factor. Maxwell presented info that their dry electrode technology offered "16x production capacity density". This could mean that in each GF there can be vastly greater production capacity. This means a much smaller footprint - if the promise translates into reality. It seems to me this 16x stat is the real deliverable of the Maxwell purchase.
Were I making such a decision, I would be tempted to wait until I had a pretty strong confirmation of the increased production capacity density increase before I finalized my land purchase.
At even 10x, it would be hard to ignore the possibility of just making all battery packs in Nevada. Maybe even buy/convert a ship to move sustainably battery packs around the world as needed. Maybe just between Eu and US east coast ports for a start.
