Solid State Battery that's baked

[Old Bear]

One solid state battery system that has already been deployed (by Mercedes, also backed by Stellantis) is the Factorial Energy design (https://factorialenergy.com). It looks quite fully baked. Would Scout consider this solution? It appears to have a considerable set of advantages.

This is a good read and summary of the current state of solid state batteries.

Overall mass production and reasonable cost are still a ways out. But it is moving.

Is there a link there somewhere? I tried clicking on every word without success.

Your definition of "deployed" and "baked" are different than mine. A quick Google search said they are aiming for a 2030 production debut. They are doing road testing but it's been maybe a year which IMO is not baked.

I am confident that Scout and other manufacturers will use the battery tech that yields the performance they need at the cheapest price. IMO that will be current Li-Ion tech (with continued tinkering around with the Anodes and Cathodes) for the foreseeable future. I expect solid state to show up first in low-production, more exotic applications and once it is baked (for years....) then into the mass market.

This is the only way t can succeed. I’ve said before-Scout will be a brand new start up and they can’t risk using a product or technology that isn’t baked. One wrong decision and/or poor judgement and Scout will be over faster than it started.
Build slow, build steady, build smart. This isn’t a $50 new iPhone that is sold for $1000. It’s the second largest investment a person will make beyond a home (and maybe a yacht or airplane if you are rich). Doesn’t have to be new tech-sure, the 10% want cutting edge but the majority of us want reliable, safe and good looking-cars and spouses-same rule of thumb.

Scout has “quantum scape” solid state batteries which is Volkswagens system’s …it’s what China is already using to achieve 800 + miles withOUT an EREV tech is reliable and here

Welcome. Good follow is @SpaceEVDriver who will likely (if you ask nicely)educate you on the pros and cons of solid state and change your whole worldly outlook on battery tech as a whole. But I suspect if it were truly baked SM would be using it-would be a no brainer, though I suspect cost would be a potential issue. Here’s hoping for sure that gen2 Scouts all take advantage.

Hi there and welcome to the community. As I said to the OP - your definition of "reliable" and "here" are different than mine. From what I can tell, no one is using these batteries in any production platform. It is all still in testing using multi-year development agreements, etc. https://electrek.co/2026/06/18/honda-quantumscape-qs-team-up-solid-state-batteries/ Because of that we literally have zero reliability data. These batteries are also not in any kind of volume production so they are not available.

I'm not trying to be harsh. SSBs may be the future, but I have been in the EV game for 16 years now and "game changing technology" comes around like clockwork. We already went through the donut labs SSB scam so color me skeptical.

 

[SpaceEVDriver]

SSBs only exist in micro devices and testing labs.

We saw the fog of lies collapse around Donut Labs as many of us predicted. In reality, know-nothing scam artists without a massive team of true experts don’t disrupt major industries like in the fairy tails.

Factorial's claims of producing solid state batteries are misleading. They’ve shipped semi-solid test batteries to some manufacturers to…test. But they are nowhere near mass production of true solid state. They’re not even anywhere near mass production of their semi-solid batteries.

Korean manufacturers are approaching the transition from test to pilot production for solid state batteries.
Chinese manufacturers are in the transition from test to pilot production for solid state batteries.

But both are being cautious and realistic about their advances. They don’t expect to ship large numbers of solid state batteries for vehicles before 2030.

More likely than not, the next big advance in battery technology will come from where none of the industry rags are looking. I could throw out a half-dozen guesses, but the nature of research and development is that the ah-ha’s come from very smart, very expert people in the labs doing the FAFO, not from prognosticators on forums.

Hard to keep track of facts vs hype - but I suspect solid state batteries do exist in test vehicles. Weather or not if they are ready for production (or only being tested to find the weaknesses), or if they are simply too expensive for production - those are the real problems. Then the secondary issue is with limited production, it will sell as a premium price until that limit is overcome.

So what you are saying is FAFO is a legit scientific method . Though, usually in the guise of R&D!

(Tongue-in-cheek)

The only difference between non-expert FAFO and expert FAFO (science) is the documentation and peer-review. If you document your FAFO, share the documentation, and then convince some other experts in that field of FAFO to also FAFO and then compare and document their results, you’re doing science.
