Toyota Claims Solid-State Battery Has 745 Mile Range, 10 Minute Charging Time (cleantechnica.com) 230

After announcing a new electric car strategy last month, Toyota is now claiming it has made a technological breakthrough that will allow it to cut the weight, size, and cost of batteries in half. The company claims it has developed ways to make a solid-state battery with a range of 1,200 km (745 miles) that could charge in 10 minutes or less and would be simpler to manufacture than a conventional lithium-ion battery. CleanTechnica reports: On July 3, the company said it had simplified the production of the material used to make solid-state batteries and hailed the discovery as a significant leap forward that could dramatically cut charging times and increase driving range. "For both our liquid and our solid-state batteries, we are aiming to drastically change the situation where current batteries are too big, heavy and expensive. In terms of potential, we will aim to halve all of these factors." said Keiji Kaita, president of the Toyota research and development center for carbon neutrality. He added that his company has developed ways to make batteries more durable, and believed it could now make a solid-state battery with a range of 1,200 km (745 miles) that could charge in 10 minutes or less and would be simpler to manufacture than a conventional lithium-ion battery.

CleanTechnica readers, being the well-informed people they are, are aware that the leap from the laboratory to commercial production is often long and difficult. If Toyota has made progress in that area, that is indeed something to be celebrated. But once again, we have to emphasize, that is a big "if." Nevertheless, our readers will want to know some specifics, things like energy density, charge and discharge rates, the number of charging cycles possible, how the batteries perform in cold temperatures, what they are made of -- things like that. They have been trained over many years to be skeptical of announcements such as this one. After all, companies like QuantumScape have been making similar promises for almost a decade, and we are all still waiting for that company to get its batteries into production.

David Bailey, a professor of business economics at the University of Birmingham, told The Guardian that if Toyota's claims are accurate, it could be a landmark moment for the future of electric cars. "Often there are breakthroughs at the prototype stage but then scaling it up is difficult. If it is a genuine breakthrough it could be a game changer -- very much the holy grail of battery vehicles." Congratulations to Bailey for using two of the three most trite phrases about new technology in one sentence. Sharp-eyed readers will notice that even with this solid-state battery news, Toyota still has modest goals for its battery-electric cars. It plans to manufacture 3 million of them a year by 2030 -- half with solid-state batteries.

  • From the quoted bits, it doesn't seem like they've achieved any such breakthrough.

    One commenter there pointed out you just have to go back over their announcements:

      In 2017 Toyota announced a Solid State Battery would be on sale in 2020
      In 2020 they said it would be here for 2022
      2023 they have same announcement again, this time for 2025.

      • Good find.
        Though, these are not totally out of line with this announcement. There they said prototype by "next year", which they did unveil, and "sell an electric vehicle equipped with a solid-state battery in the early 2020s". So 2026 doesn't fully qualify as early 20s.

      They sound like Elon Musk.

      The numbers are interesting.

      600 mile range, say 130kWh based on 65kWh cars hitting 300 miles. Charge time 10 minutes, let's assume that's the standard 10% to 80% charge, so 91kWh into the battery. Say 10% losses, being optimistic.

      That's 546kW rapid charging. Not unreasonable, but there are some caveats. To sustain that speed for even 10 minutes you will need a water cooled cable. CCS2 connector, NACS probably won't cut it. And the battery will need to be pre-conditioned to the righ

    I grew numb to fantastic masturbatory announcements of the next super amazing battery technology that would never materialize around 2010... The only one recently that I have the slightest belief in is the sodium-ion battery, because the manufacturing plant that turns them out in volume actually exists and commercially available products have been announced for sale.

      To be fair, there have been a bunch of battery advancements in the last 15 years which are shipping in products you can actually buy right now. It isn't all vaporware.

      Toyota's announcements though, they're always just an excuse for not doing EVs yet. The technology they need is always coming really soon, any day now. And Toyota's imaginary technology is always so much better than everybody else's current technology, so it'd be a shame to switch to EV right now, you should just keep driving on fossil fuels u

It must be good, right? I mean all the Toyota fan boys tell me so and option of a Tesla owner is automatically suspect.

        No single improvement to batteries has given even a 10% gain in capacity or 10% reduction of charge time - and those types of gains usually aren't the stories that news organizations pick up.

        It's the claims of 50%+ more capacity and/or 50%+ less charging time that make the news, and so far, those have all been vaporware. This one follows the same pattern as the vaporware - vagueness over what the method is, focus on the advancement in one single aspect without mentioning any of the other massive issues in t

    • Much like anyone who claims he COULD satisfy three beautiful women in bed at once, "do it or shut the fuck up."

    • A lot is happening in batteries, and solid-state is where most of the cutting edge is. Here's a link to one recent review of emerging battery technology https://www.nature.com/article... [nature.com]? It focuses mainly on robots, which require smaller and lighter batteries, but that's were advances are needed to get 745-mile charging ranges are. That said, it's going to take time to develop the technology and start manufacturing it.

      True, but usually those come from some university lab or a no-name start-up with a process that works fine in a lab but can't be adapted to mass manufacture. This is coming from Toyota so I think that it may warrant a closer look than usual.

    • The truth is there have been continuously incremental battery improvements for the past 20 years or more, those added up to the point where electric vehicles are practical and start to become affordable. Today you can buy an EV that, compared to the original Tesla Model S of 10 years ago, drives 50% farther and costs 3 times less.

  • Normally, I would shrug this off as yet another start-up from Silly Valley trying to get funding. But Toyota is a company with a good reputation as being conservative in their development and honest in their proclamations. I believe they can and will do this, and if the world can serve the demand for electricity by building more nuclear power plants, this will be the true threshold of widepsread adoption of electric vehicles.I'd short Tesla if I played that market.

    No, really.

    I could do with 100km of range. LiFePo4 would be more than adequate for the task, I think. At only 100km of range, it would be much smaller and lighter and wouldn't cost an arm and a leg.

    Now before I go to what I really am looking for that isn't available, let me say that I usually am not representative of the average customer... Somehow I manage this in most aspects of my life so yeah, what this basically is is my personal rant because nobody caters to my desires.

    What I lack is a simple car. There are a LOT of annoyances with modern cars that my asperger brain just cannot tolerate, especially given the prices of these things. Driving assistants work sometimes better, sometimes worse depending on manufacturer. I want to be able to turn them off individually. I don't want touch controls. I don't want piano black interior. I don't want a ginormous iPad in the center of my car.

    I am completely content with a car that has 2010 non-luxury levels of amenities. If the mirrors and seats can be adjusted electrically, that'll be enough. I don't need heated seats. I have never used mine even once. I don't need in car entertainment. If I have a space for my phone with a USB-C charger, in even an AUX port would do. I could attach a Bluetooth bridge myself. I don't want in car navigation that is har dto update. I don't want my car to need or even have GSM connectivity. AT ALL,

    What I want from a car is a responsive gas pedal, comfortable and quiet interior, enough space to take the family of four on vacation and sometimes go shopping at the DIY stores. I would like it to be able to haul something too.
    I would like bird's eye parking assistance and cruise control. Adaptive? Yeah, could be nice but I won't die without it.

    And I want to be able to interact with my entertainment and climate controls with honest to go buttons.

    0-100km/h in under 7 seconds is plenty, 100km range is okay. Price far under 60k CHF.

    I feel like most newfangled gadgets only inflate the price but do very little to enhance comfort and fun.

    Granted, ours is a family car and while the Mazda CX-9 guzzles 14l per 100km, it gets filled up only every two to three weeks. So yeah, certainly not standard usage. And I get that nobody will make a car for just 5000 people worldwide but I hope it's also understandable why I will not spend 60k plus on a car that annoys me when driving.

      I actually could not, as my daily commute is zero on the car (I either work from home or take the bicycle), but on weekends, I have about 500 miles to drive.

      In general, daily trips of less than 20 miles to the same places again and again cry for public transport and not for a car.

      A Nissan Leaf might be a good option for you. It seems like they are phasing that model out, as they stopped selling the largest battery version in the UK. But the 40kWh one is more than enough to meet your range needs.

      It seems to tick all the other boxes. The infotainment can be ignored and has an off button that blanks the screen. Physical controls for everything. Birds eye parking cameras. Relatively simple and reliable vehicle, easy and cheap to service, and you can do a lot of it yourself.

I could still drive on freeways and people still love the car for drifting because it’s rear wheel drive.

  • Ages ago I said Slahsdot needed that department, or an icon for it. Then at some point I decided that the battery icon was an excellent proxy for that, because almost all the "can't buy it yet" stories were battery related. Alas, no battery icon just a "transportation" one. Did I imagine it existed, or did they stop using it?

  • Any battery technology that benefits cars would benefit virtually every industry. Even if you couldnâ(TM)t compress the necessary packaging or charge / discharge control circuitry (aka bms), you could revolutionize home, grid, rv, and boat energy storage.

    This article fails the basic sniff test: if a new battery technology existed that offered this kind of specific or volumetric energy density, it would be used for almost anything and everything, not just cars.

    • Completely the wrong battery type for home and grid storage. EV batteries need to be very mechanically robust with lots of resistance to vibration, while being energy and power dense in a small light package. Grid and home storage can be very fragile and susceptible to vibration because it’s immobile, same with energy and power density, there is no space or weight requirements like a vehicle, instead the important metric is the total cost per kWh delivered over the lifetime of the battery.

      It sounds like Goodenough's solid state glass battery that was announced in 2019. The breakthrough wouldn't be in the fundamental technology - it was working on a lab bench years ago - but in developing a commercially viable production method.

  • Breakthroughs in battery tech are announce all the time, offering game-changing specs. So far, we've not seen much in the way of big leap-forward tech actually make it into the world. The promise of these sorts of batteries is always "a few years away". To be fair, this still seems better than fusion's "about 20 years away", which has been the position for about 50 years now.

      Really?

      In 2012, the "long range" capability of a Tesla Model S was 265 miles.

      In 2021, the "long range" capability of a Tesla Model S was 405 miles.

      That's what happened in a single company in less than a decade. A company that was also quite busy fighting against an incessant political fight from the rest of the auto industry while creating next-generation space travel.

      If you don't want to call that kind of advancement "game changing" on a planet infected with personal transport, then no one else should be gifted that marketing honor either.

  • Another revolutionary battery claim. Yawn.

    Assuming that the laws of physics havenâ(TM)t been repealed by a green new deal⦠If the Tesla Model S which has one of the most efficient drive systems gets around 300 miles on a 100kwh battery, and you want to 750miles it stands to reason you will need at least 250 kWh, this means you will need to recharge at a rate of 1.6 MW. Thatâ(TM)s 72 homes (100amp) at max power draw real usage is probably closer to 150, so you are looking at a subdivision per vehicle. In order to make a super charger that can service say 8 cars you are easily looking at the power draw of a small American town. Guess we are going to need a lot more windmills.
    • For home charging, you wont be able to pump out enough amps to charge it that fast. For home charging level 2, 50amp & 220v, does it matter if it takes 10mins or 6hours to fully charge? The car is sitting for like 10hrs or more and you can plug it in every day if needed to top it off since its convenient. 10min charge at a commercial charger is a huge deal since you are spending similar time at a gas station for ICE.

      People who have difficulty distinguishing between power and energy probably shouldn't crack jokes about the laws of physics.

  • If this is true it is a game changer for electric cars.

    It makes it possible for condo and apartment dwellers without their own charging stations to own electric cars.

    It makes weekend road trips possible and takes care of reasonable work commutes

    MANY charging stations will be needed. Can you imagine what things would be like at gas stations if it took each car 10 minutes to fill up?

    • Can you imagine what things would be like at gas stations if it took each car 10 minutes to fill up?

      People would have to figure out how to stagger their recharging times more. It would be a real hassle, but not insurmountable.

    • It takes about 5-10mins to fill up a gas car. If you never spent 10min waiting, you dont have a big car. When is the last time you filled up a car? Gas stations welcome 10mins to make their real $$, the convenient store sales. Here is a thought: Gas stations put in commercial chargers too.
      • I have an 11 gallon tank. I have seen SUVs take much longer to fill up, but I doubt it is literally 10 minutes. If you are up for an experiment time yourself next time you fill up and reply here. I will do the same.
        • The exact timing is irrelevant. 10mins is so similar to a gas station visit, this was their goal. Way better than a Tesla super charger visit, and no one complaining about that.
  • So what's the charging rate? If the reasonable max at the moment is 250kW, can we assume this battery will need at least 1mW?

    How will the power grid infrastructure deliver such high levels of usage? We should be upgrading our power lines now if we're expecting to support this type of load.

  • Touted range is meaningless - tell us the battery capacity in terms of kwh, not range. I get it, using range is more of an attention grabber, but range is defendant upon so many other factors. Ah, putting a range estimate in makes the reader conclude that the battery is in a reasonable "normal" type vehicle. For example, Aptera has a battery that will go 1,000 miles(its a 100kWh fyi), so what's the big deal about Toyota's announcement? But who wants to drive an Aptera 1,000 miles in a single go? Stick that

      But who wants to drive an Aptera 1,000 miles in a single go?

      The procrastinator who only cares about range because it means they won't have to be bothered with plugging a cable in more than once a month?

      You really seem to be overlooking the most obvious with today's generation. I've never seen so many drivers who will literally use their gas tank like they do their cell phone battery.

      "What? The dash says I got 7 miles left and Google says I need to go 6...I'm fine..."

    • You are wrong, no one cares about capacity. You dont drive around a battery, you drive around an entire package known as a car. Aint no consumer want to do that math. If you market 1000mi range on a full charge from a car, thats all people care about. No one gonna try to swap one car battery into another car, unless you have a youtube channel.
  • Talk is cheap. Until independent parties can verify it, this is nothing but vaporware from a big buy attempting to bully the smaller guys.

      Solid state batteries exist. They work, they've been replicated, there are still some problems to be worked out.

      Multiple car companies have announced they're going to be using them on similar timeframes to what Toyota is talking about.

  • Let's make some assumptions here... a fairly dinky 50kW motor. Let's say it's consuming full power at 100km/h for 1200km. That's 12 hours of driving for a total energy expenditure of 600kWh. To charge that in 10 minutes means you put in 600kWh in 1/6 of an hour, which means the charging rate is 3.6MW. So what, your charger runs at 3600V at 1000A??
