I think using Samsung is brilliant, and their compact and fluid design is basically what allowed R1S 7-seaters with the longer range capacity that was previously not announced.

Samsung is conglomerate, so Samsung subsidiary that makes your washers isn't the same subsidiary that makes your sell phone, but they might have a third samsung subsidiary in common. If you were ever stationed in Korea, you would learn pretty quick how big Samsung is. A person can be born in a hospital built by samsung using samsung construction and medical equipment, go to a school built by samsung and use Samsung technologies, live in a house full equipped with Samsung devices and appliances, then work for a Samsung company, and when they die, Samsung even takes care of funeral services. Other than military vehicles, and we owned a Samsung car back in the day.

A common factor between a lot of those products in the battery packs, so I am sure they went through a lot of testing and variety of applications, not to mention it will give Rivian the opportunity to be the sole consumer in the EV market without having to compete with other manufacturers who use LGchem/Panasonic.

I'm actually a Coastie, or as y'all lovingly call us, a puddle pirate.
It was either Marines or USCG for me and my college roommate make it an easy choice: "You can either take lives or save lives."

How about them Samsung batteries?

I did not know that! I think because last I heard BMW signed with some Swedish company and Fiat as a brand isn't a major player yet in EV world. But it would be interesting how Samsung manages both if they exapnded.

I don't want to cause any distress, but I'm very doubtful Rivian will have Samsung's SDI gen5 batteries, if they plan on keeping their battery pack design the same with 21700 cells.

It seems like Gen 5 cells are for stack method cells, aka square cells and not jelly roll aka cylindrical cells

"Samsung plans to make Gen 5 batteries using the stacking method instead of the traditional jelly roll method. Therefore the company is planning apply the press notching first, which it has more stable technology in, considering it is trying the new stacking method."

However, if they ditch the cylindrical cells... everything is possible.

You haven't caused any distress and Rivian won't be ditching the 2170 cell at this point. Good callout on the "gen5" seemingly being in reference to their prismatic cells. Details of SDI batteries are scarce and it is difficult to determine if "gen5" primarily refers to format and manufacturing process or chemistry or both. I was looking at gen5 from a chemistry perspective and hoping that SDI continues to improve upon their high nickel content NCA cathode.
