I wouldn't call solid state batteries 'vaporware'.
Are they shipping? Can I buy them? Are they available in anything beyond a research lab and press releases? Has anyone actually seen prototypes of them meeting anything resembling claimed range?
No?
Then I stand by what I called them. A press release about some promising lithium battery development is a dime a dozen, and I'm sure you could automate them with some LLM - every 6 months, release some new gibberish that journalists will chew up and regurgitate. Good for a stock bump, certainly.
Toyota does not have any solid state electrolyte batteries shipping today, and as I read their road map, won't until at least 2027 (though they're working on some other interesting things that they claim will ship sooner).
The Toyota Motor Corporation has always been known for its commitment to innovation and has continued to lead the charge in most automotive developments in the 21st century, most recently the solid-state battery technology. The company is working towards bringing solid-state batteries to the market as early as the mid-2020s, which will be a significant milestone in the EV industry. The company has been toiling on this technology since 2012 and created a team of over 200 dedicated engineers and as a result, has over 1,000 solid-state battery patents.
Are you asking ChatGPT about this or something? It's a bunch of well crafted nonsense that says nothing of interest while hedging it well. Or is that just straight out of one of their press releases?
Patents don't mean much, IMO. You can patent all sorts of nonsense without actually being able to do it.
Toyota's target is to get their solid-state batteries into their hybrid vehicles first before their all-electric offerings. Toyota has a target of about 700 kilometers (435 miles) of range on a full charge which seems to be the key advantage of the solid-state technology over traditional lithium-ion batteries.
"Target." As in "Dream, hope, press release." Not "Demonstrated capability." And... the modest density increases aren't really any of the exciting bits about solid state electrolyte either.
"Not buying a car that meets your needs now because Toyota has promised something cool in the future, and already slipped on their dates for delivering it" doesn't seem wise to me.
