The industry would have been very skeptical of such a breakthrough device except for the developer. Dr. Goodenough won the Nobel prize for the Li-ion battery. And the numbers claimed are quite sensational.
And there are a half dozen other groups attempting to bring such a device to market. I would also think it very likely that we will have a good view of what is going to happen this year and next.
My view is a shippable device is virtually certain. Then we see what the parameters of the device really are.
And the initial device will not be the last word. Take at least a decade to get it to its best state. The most interesting thing may well be the intellectual property outcome. Who owns the key patents?
Yes, there are a number of prominent groups working extremely hard on solid state batteries and who report they are making strong progress. They may not all succeed in making a compelling device, but they won't all fail.
And before solid state batteries, we'll see both GM's Ultium batteries and Tesla's 4680 batteries in the next 3 years, and which are already said to be a big step forward over today's batteries.

Tht is pretty much all dealing with management of the battery pack rather than the physics of the battery. Sounds like good stuff but not doing anything to improve the basic battery.
The solid state batteries particularly the Goodenough cell are very big changes to the cell. No more fires for instance and no need for fire proof mountings. And the Goodenough cell is purportedly offering much longer life, quicker charging, lower weight and heavy discharger capability.
2022 Bolt, $32,000 EPA range of 260 miles.
2012 Nissan Leaf, $35,000 EPA range of 72 miles.
Not a huge price decrease since it was offset by the battery just being a lot larger. Nissan hasn't done a great job with the Leaf, but then they don't need to since they still have the tax credit and discount them like crazy. Still same price just the base model is now around double at 149 miles rather than 72. Since they're around $9,000 off MSRP plus rebates, puts it around $20k for 149 EPA range.
Back in 2017 if you needed a new battery for a Bolt from the dealer it would have costed you $15,734.29
I get the feeling it wouldn't be any cheaper today.

Ultium uses improved battery materials, with an "NCMA" - nickel, cobalt, manganese, aluminum cathode that reduces the use of expensive cobalt by 70%, as well as improved "pouch" packaging and a wireless battery management system. It will be significantly lower cost and higher charge density than the existing batteries in the current Chevy Bolt.

Sorry it will burn and lacks any of the new capabilities of the solid state.
And it will simply get crushed by any of the solid state
However some of the stuff like wireless control may work. Small deal but real..

Solid state batteries are great, but they're further out. The Tesla 4680 and GM Ultium will be rolled out in production cars over the next 3 years and will be a big advance. There are a lot of differences, but both use NMCA cathodes.
GeoffD is right. Here is a plot of lithium ion battery pack costs over the past 10 years. You are claiming that cost should be going up, but it's been going down, way down. And over the next 5-10 years, further significant reductions are expected based on what's been disclosed about future designs:
Would you please tell me the price of new EV battery in 2021? The cheapest one you can find will be fine.
Also, in reference to my post above: not too long ago automobiles of all kinds didn't cost as much as they cost today. A lot of people don't take into consideration that labor and construction costs (mining for the metals needed, plus delivering the products to the factory, and then delivery to the dealership) all become greater from year to year. An EV battery may be cheaper today than they were a few years ago-mostly because of federal incentives, but even the cheapest one on the market is expensive, because metals and plastics aren't getting cheaper any time soon. Supply and demand will dictate the price in the market, but as the natural resources dwindle, products become more expensive.

Solid state batteries will still need metals, including conductors, and plastics. The main difference is that there are using solid electrodes and electrolytes. The saying that, "there is not such a thing as a free lunch" is true. There are several government programs that offer deductions for buying energy efficient and "green technology" products. But the tax and other monetary incentives don't grow on trees. It comes from the tax payers. https://en.wikipedia.org/wiki/Solid-state_battery
Battery prices have dropped 10x over the last decade. Batteries were north of $1,000 per kWh in 2010. They’re approaching $100 now. It’s not unreasonable to expect the price to fall to $10 to $20 in the next decade.
It is. Battery costs have come down quite a bit. That's why you can get a new Bolt for $19k. If the rest of the car (including electric motor) only cost $2000, then why do they charge $18-20k for a gas powered car?
In fact, GM is releasing the E-crate system for converting other cars that included battery pack, motor, trans, and battery controllers, motor controllers and wiring all from the Bolt for use in hot rods and custom cars later this year. It will cost much less than a Bolt, as otherwise you could just buy a Bolt and swap the parts over.
