This looks like someone has taken Toyota's press release and reformatted it into a news story.
The reality is that Toyota has been working on solid-state batteries for the last 10 years. Back in 2017 they claimed they'd have them in vehicles by 2025, and now they say it'll be more like 2027-2028 -- so this is really an announcement of a delay wrapped in positive language.
Solid-state batteries have significant advantages for EVs -- primarily a significant boost in energy density. However, I don't expect that we'll see them on the market until near the end of the decade, probably appearing in a few 2028 or 2029 models, and more widely available in the first f ew years of the 2030's.
I'd expect that by then we will have stabilized on a preferred EV range and will be well on our way to having a charging infrastructure to support it. This should greatly reduce range anxiety. So rather than enabling 600-1000 mile ranges to address range anxiety, I'd expect that when solid-state batteries do arrive, they will be used to deliver "normal" (300-500) mile ranges with smaller, lighter, and cheaper batteries.
It is inevitable that electric storage technology will improve. The article states "may have solved the range and battery weight problem". These are pretty bold statements and I expect there will be some weight behind it however they still need to solve the safety issues. If it can charge in 10 minutes, it can also discharge that much energy very quickly making it a watch item for safety and a few hurdles that will need to be managed through the standards organizations.
This is exciting news and it will be interesting to see when/if it becomes commercially available. Now we need some competition to kick things into gear.
So here is a question. Who would be silly enough to strap a tank of highly explosive liquid right on top of very hot pipes?? I ride my motorcycle almost daily ;-)
Cold fusion reactors have been “5 years away from commercial viability” for the past 25 years. Solid state batteries seem to be following a similar trajectory.
First question to ask is did they actually manufacturer a cell.
Second question (most likely doesn't have to be asked based on question 1) what is the capacity of the cell you have actually manufactured.
If it is below 20 Ah, then it is still a lab sample/prototype. If it is over 20 Ah, then question 3 is when will you be able to scale it to a useable capacity for manufacturing.
