Rivian’s R1T pickup and R1S SUV will both use the Samsung SDI battery cells.
Just on the trail of other big battery news in the US (and globally), we’ve got news today from Rivian that it will be getting its batteries from Samsung SDI.

Naturally, the news doesn’t come out of the blue — it’s not like buying new pencils. Rivian and Samsung SDI have been working together as Rivian’s electric vehicles have been getting developed in order to make sure the vehicles are designed well and the vehicles and cells play nicely together. As the two put it, “to ensure robust cell testing and characterization.”
