Thanks for sharing!

I know less than nothing about battery tech development, but they will need to improve the operating temperature range to put those batteries in cars anywhere but in mediterranean climates

-22°F to 113°F should be able to operate year-round in most US states, no? And that's without taking into account e.g. active temperature management.

Personally, I wouldn’t want to rely on tech that could be finicky on a randomly crazy cold/hot week even in my home state of NY.

Didn’t think of active temp management, for sure! That would make it more possible!

The last time Stellantis proudly announced ā€œBreakthrough battery technologyā€, it was when they added that ā€œinnovativeā€ auxiliary battery to Jeeps. I hope their solid state battery design is better than their POS start/stop design.

A little quick digging and I found that there are 16 or 17 states where the average low temperature each year is less that -22° at least somewhere in the state (with the Adirondack region of NY being one of them), so fair concern. That said, at -20° diesel would be a little sketch also without some kind of temperature management.

Yes! Solid state ESS for all!

Achieving that temperature range w/o active temperature management would've been a huge advance indeed. But that's not what they said. And it's the need to continuously dump energy into batteries to keep them acceptably warm and/or cool at real world temperature ranges that makes them a non-starter in most applications.

Parse the following statement and once you figure out what it is they're actually saying, this press release takes on the appearance and aroma of a nothing-burger. Which, coming from Stellantis, is par for the course:

This surpasses previous solid-state limitations and opens the possibility for better performances across various climates.

Is that not what they said though?

"Factorial’s scientific engineering and AI-driven tools developed the latest electrolyte formulation that allows the battery to perform in temperatures ranging from -30°C to 45°C (-22°F to 113°F). This surpasses previous solid-state limitations and opens the possibility for better performances across various climates."

That mentions the electrolyte formulation allowing the expanded temperature range. No mention of active temperature management required to operate in those temperatures.

I mean, it's a possibility because it's still in the experimental/development stage. If they've only tested it at different temperatures in a lab instead of actually in different climates, they can't say that it works in different climates, just that it works at different temperatures.

It’s also just a possibility because 113°F is still pretty limiting to actual climates. And no, not just places like Phoenix. Asphalt is often way hotter than the air temperature, and battery storage is usually right next to it on cars.

Not discounting the advances to get that range, but the batteries themselves (without temperature management) won’t work for tens of millions of people during summer in the US alone. And this announcement is scoped to batteries, not a fully engineered solution.

We need a battery technology that performs almost similar between -20f-130f, reaches 80% charge in under 30 minutes, lasts 200 miles minimum (under all conditions except track use), and doesn't explode the second it's punctured. The current Lithium-Ion batteries are way too unstable for road vehicles. Yeah, they work, but they're not ideal in the slightest.

The biggest issues EVs have in the states is they're only optimal in a very few select cities and areas. 90% of the country isn't EV friendly purely from a geography standpoint.

Funny you mention this… I have a 2021 two door 2.0 with the stop-start, and still with the original main and aux batteries. Up to about 34,500 miles now, and no issues so far… šŸ™„

But anyway, I don’t drive many long distance trips; I drive mostly short mileage around town and due to living in New England, use heater or AC pretty frequently. So… for whatever reason - I’m guessing it is due to the lack of long duration driving - my Jeep hasn’t actually done the start-stop thing in years. Like, literally 2-3 years since it did it or even gave me the dashboard ā€œstart stop readyā€ message. I personally don’t like it, so just considered myself lucky that it stopped working, and have basically forgotten about it at this point.

Well, yesterday morning, my wife and I took a 100 mile, mostly highway, round trip up to the Boston area, and came back. And we had climate control off for basically the whole trip. Later in the day, I’m driving somewhere else, stop at a red light… and whoa… stop start worked! I was like, ā€œWait a sec, what was that?! Was that what I think it was?!ā€ Next red light, it did it again. And then a couple more times on the way home. 😳 Damn. This sh!t still works?! So disappointing. And here I thought I was magically off the hook! Guess after years of catching a break, I’m gonna have to start using the ā€œdisableā€ button again. šŸ˜‚. At least until the aux battery level becomes ā€œless chargedā€ again.

Temps here in Southern Nevada often exceed 113 degrees in the Summer and are getting hotter each year. While this might be considered a "breakthrough technology," I'm not so sure it will accommodate everyone's use case. Interesting tech though.
