Yes, there is so much blind hate in this forum. They refuse to accept the technological advancements that Chinese EV makers are making, and love to denigrate Elon who single handily keeping EV revolution in the US soil. I see replay of 1980’s when Japanese dominated the auto industries. Without trade barriers, Chinese EVs will decimate US auto industries including Rivian.In complete agreement about SSB. Tesla also except that you're on Rivian forum with lots of anti-Elon member so you're just starting a pissing contest.
Having worked over the years with NASA and DOE on electric aircraft, the state of the art battery density by 2030 is projected to be around 500w/kg with SSB.
The issue is scaling from small prototypes to large scale deployment, while achieving consistent reliability and power cycles.. I believe the story of this SSB-based vehicle is a vision concept that's intended to grab attention. Where the rubber meets the road, it may have a small SSB with lots of Li-ion or LPF batteries, if it comes to market within the next year or two. The real telling part is:
"130-kilowatt-hour solid-state battery with 621 miles of range on the overly optimistic CLTC range."
With 130kWh, SSB, it should be able to go well beyond 700 miles for a sedan that looks like what is depicted. Reason being that SSB energy density is almost 2x of conventional LFP - meaning that for the same kWh, SSB would weigh about 50% less.
For a comparison sake, the Air Dream Edition has a 112-kWh battery pack which will provide an estimated 520 mi (840 km) of EPA range and is Li-ion traditional batteries. The vehicle in question has more CLTC range which is far more optimistic than EPA's and has larger battery pack to get about the same range.
Clearly not SSB.
