I have seen mention here about solid state batteries, but lots of negative remarks about it being way out in the future. I haven't seen any mention of this article about Samsung? https://interestingengineering.com/energy/samsungs-ev-battery-600-mile-charge-in-9-mins

I think we all pretty much just have an "I'll believe when I see it" approach to these new battery announcements.

That are cheaper or higher energy density than current LiFePo.

Solar Joules are catch and release
I've been watching the solar and battery industries for four decades now, and there's a new announcement of something that'll take over the industry and provide power too cheap to measure every month. It's a long road from the lab to the Amazon cart. LFP batteries were 'invented' in 1996. You do the math.

Personally I have no interest in being a guinea pig for new tech, first of any kind is always overpriced and unstable a risk I'm unwilling to undergo. Time will tell if it is a suitable replacement.

You can tell the pioneers, they are the ones with the arrows in their backs.Personally I have no interest in being a guinea pig for new tech, first of any kind is always overpriced and unstable a risk I'm unwilling to undergo. Time will tell if it is a suitable replacement.

its not called the bleeding edge for nothing
and hadn't looked into/realized LFP was that old... ugh... but not surprising

The "Future" IS HERE
Yoshino Solid-State Portable Power Station B4000 SST, 2611Wh Backup Battery - these are available now on amazon & other places, if you have $3300 to spare. I would love to have 2 of them to replace my 20 year old gas powered generator. There are 3 smaller sizes available too, starting at 330W for $300
You can also buy individual solid-state lipo cells in capacities up to 67Ah per cell with cost running around $2.15 to $3.25 per Amp hour through various Chinese marketplaces. Once Samsung gets ramped up, then we should see that cost per Ah start to drop.

I've seen a few reviews of these Yoshino Power Stations.
Actually pretty impressive, nice design.
They boast thier battery is Solid State LI-NCM.
Do we really know the safety and cycle life of these types of batteries?
Not to mention these units are way over-priced.
I think I'll stick with LFP for a while...

At this point it seems the solid state batteries are more geared towards the EV industry with the high C rates I really don't see how they would be of much benefit in solar energy storage.
But regardless I'm sure somebody will have to do it just to be the first.

Seems like a step backwards, as we're trying to get away from strategic metals like cobalt and manganese.

They will be great for EV's if you can actually pull up and get a full charge in 15 Minutes.
Also the Weight and Space savings will be a huge plus for EV's.
For Home Solar it's hard to see any positives.
Energy Density: Not a factor unless the Price is close.
Operating Temps: Nice but not worth paying more for.
More Cycles: Will Calendar aging improve? Is this getting so long in time that tech Obsolesce will make it irrelevant.
Not Combustible: Good selling point that could make them a requirement, but I don't see that happening in the next 15 Years.

Are Lithium Ion solid state batteries non-combustible?

Good question, I think they are to a certain extent.
All the tests i have seen show that all of the normal tests like puncturing them or hard charging don't seem to cause any fires.

I sit in a similar position.

Indeed. Though I won't be buying them on Amazon, or AliExpress, or Temo or eBay, it'll at least be an indicator that they have reached commodity status, and the offerings from the EG4-like businesses extant at the time will hopefully be pretty stable and have (almost?) all the bugs worked out.
Also: Not sure I'm going to live that long. 8*)

I think the situation is people come up with new battery types, but its too hard to scale them in mass production.

Why does a 660W 120V power station have 5-20R receptacles?
Even one of them, running 120V at 20A is 2400W.
Misleading marketing?

Solid state batteries are for sale now but they have very low capacities. The theoretical performance of them is yet to be seen.
There are several companies doing vehicle sized ones, the best ones I've seen all have even slower charging than some lithium types of batteries do today.
The next battery tech for cars will be some lithium sulfur which should greatly increase capacity and discharge of them. I think you will see that well before you do solid state.
We'll get to a point where lithium sulfur is for performance EVs and LFP is for ordinary ones..
Just like sodium ion and graphene capacitors which do exist and can be bought now. The real excitement is when you can actually buy the stuff. They took 30+ and 10+ years respectively.
