Japanese firm believes it could make a solid-state battery with a range of 745 miles that charges in 10 minutes
They have been “claiming”/ “announcing” this breakthrough since 2017 repeatedly. They STILL haven’t figured out how to mass produce it affordably to making it meaningful. They keep pushing out the date for when it will arrive for many years now.

- Attract investment money

Repeat until product is complete or no one will invest.
Since Toyota is way ahead with hybrids but behind with EVs, this would be a way to tell the public, “wait, don’t buy a competitor’s EV, because we’ll have something 100x better in a year or so.”
I hope I’m just being cynical, because solid state batteries do sound awesome. I wonder was the weight difference would be
I’ve wanted to believe in breakthrough battery technology so many times and been let down. I’ll wait until it hits the market before getting excited. Even this article is pretty vapor-ish:
The world’s second largest carmaker was already pursuing a plan to roll out cars with advanced solid-state batteries, which offer benefits compared with liquid-based batteries, by 2025.
Then a little further down:
The company expects to be able to manufacture solid-state batteries for use in electric vehicles as soon as 2027
I’m waiting for the,“By 2030 we’ll definitely be able to use these batteries in our 2035 models. You’ll see this in 2040 and the sky will open up with sunshine and birds will sing.”
last year it recalled 2,700 of its first electric vehicles because of concerns the wheels could fall off.
I set up the production line for this hub unit. This news has been really annoying because it meant we had to scramble to install a bolt press machine on this line.
It sounds like you’re implying you wouldn’t have had to install it without this news breaking. Is that the case? I’m curious about this topic if you care to elaborate. What is a bolt press machine? How has this news affected you?
A bolt press is what it sounds like. It presses the studs into the hub unit (idk why we call studs bolts). I think we, as a company, knew about it before the news broke. We had to re-configure the line to add a machine that wasn’t there originally and now we need to changeover between the bolt-type and bolt-less. This changeover is more involved than you might think since some of the components were redesigned for the bolt-type, necessitating some new tooling.
Yeah, chuck in on the pile of “battery innovations” that get announced but never come out. It’s a large pile.
Hydrogen is the future.
Why do you feel hydrogen is the future?
From my understanding, it’s more of a fuel than a storage medium so they kind of play different roles. On top of that, I thought it’s currently pretty difficult to store outside of pretty extreme conditions and the best way to create it at the moment is by burning fossil fuels (natural gas).
I’m not an expert, so let me know if I got any of that wrong!
Oh fuck off with that charging times.
Assuming this battery will be 150kwh (which is a conservative estimate for such a range)
Let’s ignore even heat loss So you need to 150kwh in 10 minutes, wish equals to 900kw of immediate charging speed.
Now imagine 20 of those power inputs connecting/disconnecting on a local power management substation.
Not fucking gonna happen.
The quickest way I’ve found to separate the articles that are going to be meaningless waste-of-time fluff pieces from ones that might be informative is to find the verb in the headline.
Is it something like “claims”, “calls for”, “praises”, “criticizes”, or “expects”? Fluff. If something deserving of a more concrete, direct verb had happened, the headline would have said so. Verbs like “slams” or “attacks” or “demands” are even worse; they’re aggressive and enthusiastic about their content but still can’t make the claim something actually happened or changed.
If the verb is preceded by “could”, “might”, “maybe”, or similar, especially with regard to tech news, it’s also probably an empty slow-news-day article, but those words aren’t necessarily as hollow as the ones mentioned above. Sometimes they’ll contain interesting information about the current state of things, even if they’re just going to lead you on a merry speculation romp about the optimistic/horrifying future.
The important question is what is so wrong with the now countless existing 200/300 mile evs that charge in less than 30 minutes?
300 miles isn’t enough distance for a day of travel and lots of places don’t have charger availability still. What’s wrong with approaching parity in user experience to gasoline vehicles? It will only accelerate their use, and 700 miles in winter is going to be only maybe 300 miles.
A 30 minute charge for every 4 hours of driving is already practical for a long drive. Every safety organisation and fatigue management plan on the planet says you need to stop more often than that for fatigue anyway.
If some is regularly driving more than 200mi/320km in a day (more than the average car drives in a week) without a break on those trips, then a hybrid car is probably a better bet for the foreseeable future.
Hmm I thought Toyota was focusing more on Hydrogen powered cars as a long-term strategy rather than EVs.
Yes, in the US they have gone so far as to lobby against EV adoption and run anti-EV commercials in favor of trying to get people to buy their hybrids. They innovated earlier with the Prius but then stagnated and are behind now and instead of trying to catch up, they spent time and money trying to block competition. Really made me dislike the company despite the stellar reputation of the quality of their vehicles.
Especially since hydrogen as a fuel is a dead-end, so far as I can tell. In addition to the net energy loss that come from separating hydrogen from whatever else it’s attached to in the precursor material (please tell me they’re not using water for this…), who is going to want to drive a 2025 Toyota Hindenburg?
