Prieto Solid State Battery Also Claims Breakthrough

We feel like we’ve heard this countless times already, but here we go again.

A report in Japan’s Chunichi Shimbun claims Toyota is working on a new type of battery that will allow for significantly increased driving range and reduced charging time.

Quoting the newspaper, Automotive News says the battery will be used in an all-electric vehicle that will be based on a new platform and will arrive in the beginning of the next decade, most likely in 2022. The battery will be solid-state, which means it will use solid electrolytes rather than liquid ones for safety reasons.

Most of the current lithium-ion batteries need at least 30 minutes to recharge to a certain charge level (~80%) and can offer total ranges of up to 250 miles (400 kilometers). Toyota wants to reduce the charging time down to the time spent for reloading an ICE vehicle.

According to the Japanese newspaper, the new electric vehicle will be launched at first in Japan in 2022. So far, Toyota has declined to comment on the report.

“There’s a pretty long distance between the lab bench and manufacturing,” CLSA auto analyst Christopher Richter commented to Automotive News. “2022 is ages away, and a lot can change in the meantime.”

The automaker plans to start mass production of electric vehicles in China by 2019. The first model to reach the production lines won’t be a dedicated electric car and will be based on the current C-HR. The crossover will be re-engineered to accommodate an electric motor and a battery pack, located somewhere under the floor.

For long years, Toyota believed plug-in hybrids and hydrogen fuel-cell vehicles are the future, but last year the company decided to switch its focus on completely electric vehicles. A new in-factory division, headed by president Akio Toyoda, will work on those EVs.

  1. SJC says:

    Solid electrolyte is the electrolyte and separator in one membrane, no leaks no fires. A good idea if they can make it work.

    1. SparkEV says:

      They will make it work 5 years from now. Then after 5 years, it will take 5 more yeas to make it work. Reminds me of H FCEV.

      1. Pantarei says:

        According to The WSJ and Chunichi Shimbun, Toyota is in the “Production engineering” stage. No further info in the article though.

        1. SparkEV says:

          Applying my alien proof test, I’ll believe it when I’ve eaten it and squeezed it out the other end. Until then, nothing.

          1. SJC says:

            We could have done without that visual…

      2. unlucky says:

        I worked on a project in 2006 which was designed with the idea that solid state batteries would be ready in 2008.

        They of course were not.

      3. Robert Middleswarth says:

        The problem is they can’t really push EV out much further. Solid State batteries might not be ready but they are going to have to have good EV ready for the market by that and I think they have figured that out. What they are doing is tiring to save face for not working on EV’s sooner.

    2. Mikael says:

      Fires are irrelevant. Safety is not an issue.

      But if they have other advantages then any slight saftety improvement is of course also welcome.

      1. Pushmi-Pullyu says:

        Safety is definitely an issue. The fact that multiple EV makers have been able to deal with the problem and minimize it, doesn’t mean it’s not an issue; it just means the EV makers have really good engineers.

        Anyone who has seen a video of a li-ion battery fire in a laptop or a cellphone, or one of those cheap “hoverboards”, knows that the fire hazard of li-ion batteries is a very real issue.

        Solid state li-ion batteries will be a significant improvement in several ways, for everything powered by li-ion batteries. One of those ways is greatly improved safety.

        1. Tom says:

          It is not an issue relative to the dangers posed by gasoline engines, which are considerably more likely to result in injuries due to fire.

          1. john Doe says:

            Not a major problem with diesel. .

            But solid state batteries is a key for car manufacturers. Car ferries have regulations on where EVs are located at ships, and how many at one location. That will change with solid state batteries.
            It will also give the designers and engineers more freedom since they can get preshaped batteries to fit profiles in the vehicle.
            Squre battery packs are OK, but have limmits.

            We got solid state batteries from a Japanese company (and a US university) many years ago at the university. They used the batteries for testing and show how they worked.
            So there is no problem producing them. Industrialisation of the process, energy density and price is key for a battery.

            We got a list of some of the challenges they had – and from time to time we got updates on how they solved the problems. It was everything from material choise due to price or performans, to how they could produce it automatically, and scale it up.
            Later we got a battery (pre shaped) from a Korean manufacturer. That was shaped to fit a tool.
            We heard rumors that Sony had a prototype of a portable audio device where the housing was the battery. The teacher also told us that it would be possible to shape the battery like the housing of a game controller.
            I’m not sure if there are any advantages in that case, as injection moulding of plastic is fast, cheap and highly automatic.

            At the university we got another sample from a Canadian company, coupled with a fuel cell.

            So there is no question solid state batteries will come, but when is the question.

            I think it will come when all the large car manufacturers release their EVs.
            Time goes by quickly, but 2020-2022.. I’m sure we will see it then.

            I’m also pretty sure Panasonic as a major battery manufacturer have a lot of R&D in solid state batteries. I’m also pretty sure that a company like Tesla have plans to incorporate solid state manufacturing in a new part of their joint venture battery factory.

            There will probably be regular and solid state battery EVs side by side for at least a decade – after the first cars with solid state comes to market.

            1. pjwood1 says:

              Much safer to hop a ferry with only EVs, than one with gas cars whose fuel is still under pressure, and whose oil may be dripping on the exhaust manifold. Those things burn up all the time.

              Tesla doesn’t think beyond the R&D curve, for batteries. Elon’s “Send us a cell” comes from all the smoke, like Toyota blows, without being able to produce a convincing demonstration, patent and commercial viability. The 5-year rolling BS window is something we can all count on.

              1. john Doe says:

                I got to keep the Canadian fuel cell with the solid state (10x10x2cm) battery under it.
                They made that model between 2004 to 2007, and it still works perfectly today.
                I’ve added a solar cell unit to it, and use it to run some LED ornaments and lights in the garden, for the kids. The fuel cell is housed in transparent plastic, can see through it and has a blue LED in it.
                It was a model sold to universities all over the world, with your typical banana plug electric connections.

                I’ve added a solar cell to it, to charge it up. The battery stores the energy. Once in a while I run the fuel cell too.

                The fuel cell works properly – but it’s an old fuel cell design and they work poorly in winter in the coldest periods.
                I wonder what the lifetime of the product is.
                Anybody that knows the lifetime of a fuel cell?
                As far as I know there is no degradation on this battery. This was “hand made” and clearly not an industry product if you look in the square battery case.
                It was not cheap to buy back in the day – but I thought that was primarily because of the fuel cell (which was full of expensive materials back then). I know that educational models of higher quality is expensive. It beats all the low cost variants on quality, and few things aggrevates me more then crappy quality (buying junk). The expensive models is usually worth the price.

                I’b building a charger, and a regulator to use solid state batteries in an electric RC car this winter. I’ve just etched the PCB, and will make a test of my design. I’ve already simulated it on the computer.. but you never know 100% before the prototype works.
                I bought the battery from Korea, and it looks more like a professional made battery. Not that I’m going to open it up – since it was expensive with shipping, tax and so on.
                I’m sure they could group batteries like this together, and get a car moving.
                Price will fall as production volume increases, I guess.

    3. speculawyer says:

      It needs to work.
      And be safe.
      And be manufacturable at large scale.
      And be cheap to manufacture.

      Lots of hurdles to clear. I hope they can pull it off…but I’m skeptical

  2. WARREN says:

    Why can’t solids still overheat from a short circuit and combust? Just look at magnesium. I mean in a bad car fire, everything burns down to the shell. Is the battery made of flame retardant compounds?

    1. SJC says:

      Many solids melt at high temperature then vaporize at even higher temperatures, they are not flammable like many liquid electrolytes.

    2. Pushmi-Pullyu says:

      WARREN asked:

      “Is the battery made of flame retardant compounds?”

      I don’t know about the tech that Toyota is touting, but Ionic Materials’ solid state “plastic battery” is indeed made of flame retardant materials, as seen in the “Search for the Super Battery” episode of PBS’s “Nova”.

      The documentary shows the plastic battery being set on fire, and the flame simply going out because it’s flame retardant. Once you get rid of the highly flammable liquid electrolyte, this becomes possible.

      http://www.pbs.org/wgbh/nova/next/tech/new-damage-proof-battery-has-higher-energy-density-wont-explode/

    3. Ben says:

      Liquid electrolytes tend to be unstable and like to react in exothermal reactions at elevated temperatures(150-200°C) and at high and low potentials (4,4V). Because of being liquid, all the material can get in contact. As well they boil at low temperatures which generates a mix of highly flammable gases and steams under high pressure.

      To keep it safe and controlled you need to invest a lot of material in structural ruggedness, reasearch and testing.

      Liquid electrolytes react with the active materials in the cell, which is a problem for performance and its lifetime. Luckily these reactions form a passivation layer, which slows down further reactions and make cells usable today, but again depending in temperature and potential this layer can get dissolved or grow.

      All these issues do not exist when using solid electrolytes, which promise to be lighter, safer and maybe could have a better cycle life in the future.

  3. Pinewold says:

    Translation not interested in EV’s beyond token efforts for at least 5 years!

  4. David Murray says:

    While I tend to think of this as stalling tactics, I do give Toyota more credibility than some startup battery manufacturer that’s trying to raise their stock price. If it is true, I’d be curious how much better it would perform. For example, if they used those in the Prius Prime, which would be nearing the end of it’s production run for that body style, how many miles of EV range would it have? 35? 40? Either way, that would make it more viable. And obviously when used in a pure BEV it would be great too!

    1. john1701a says:

      Establishing a plug-in reputation with Prime in the meantime makes sense. They’ll have all of the EV tech itself already proven in the minds of dealers & consumers, making the high-volume investment in solid-state batteries a reduced risk for the business.

      Basically, it’s a chicken or egg situation. We know how under-developed the infrastructure is for plugging in the still. Why not get the vehicle tech well established in the meantime?

  5. Pantarei says:

    The same article says BMW plans to introduce solid state batteries within 10 years. Which doesn’t suggests 2022-ish. I thought BWM and Toyota had a battery development partnership, but apparently that only concerns lithium-air batteries not solid state.

  6. koz says:

    OMG! It’s the “we’ll get off our azz and do something in 5 years” ploy. How original. Hopefully the US fed EV tax credit is restructured by then and Toyota cars enjoy the credit they will deserve at that point. NOTHING!

    1. john1701a says:

      Like GM not delivering a SUV using the same tech in Volt until 2022.

  7. SJC says:

    SAKI3 has solid state, now they may be used in high priced Dyson vacuum cleaners. When they started with deposition I figured they would not be cost effective for cars.

  8. Chris O says:

    But..how could it compete with those $500 fuel cells fuelled by $1/kg hydrogen it will launch that same year?

    Well, only in an alternative reality in which one can put a timeline on technological breakthroughs.

    1. Pushmi-Pullyu says:

      LOL! 😆

      A non-subsidized price of $1/kg hydrogen fuel would indeed have to happen in an alternative reality, where the laws of physics work differently!

      1. SJC says:

        Takes about $1 of natural gas to make 1 kg of hydrogen.

  9. Don Zenga says:

    Read this line.
    “So far, Toyota has declined to comment on the report.”

    So nothing is confirmed, still Toyota is not interested in plugins, that’s why the newly redesigned Camry has only hybrid and no plugin version.

  10. Rich says:

    As Musk repeatedly points out, technology does not move forward without large amounts of talented people focusing on the technology. I’m thrilled Bosch, Toyota, Samsung SDI, Panasonic, LG Chem, Dyson, etc. are all focused on achieving the next battery breakthrough. If Toyota thinks they can bring solid state batteries to market in EVs by 2022, this is amazing news. That means the death of ICE powered new vehicles by 2025ish. The more the merrier.

    1. Pushmi-Pullyu says:

      “As Musk repeatedly points out, technology does not move forward without large amounts of talented people focusing on the technology.”

      That’s not always true. For example, the solid state blue laser was developed by one guy working with a very few assistants.

      But it’s certainly true enough to be a rule of thumb. The days of the lone genius working in solitude to perfect his device are, for the most part, long gone. Most of the easy to invent breakthroughs have already been made. The harder ones generally take a team of dedicated scientists and/or engineers.

  11. Pushmi-Pullyu says:

    When some company says that some breakthru tech is coming in five years, what they really mean is “We hope we can commercialize this tech within a few years.”

    When LG Chem announced what they called a “200 mile battery”, they were actually ready to take orders for delivery in two years, because they knew at that point that they could indeed make the batteries on a commercial scale at a competitive price, and it was merely a matter of building out and fine-tuning the production lines.

    There are now multiple claims for solid state batteries with prototypes which, apparently, actually work reliably. At least one of those claims appears to be reliable, and perhaps more than one.

    The race is on to commercialize the tech. We don’t know who is going to win, but at the risk of abandoning all the skepticism about breakthru battery claims that I’ve learned from too many years and far too much time spent on TheEEStory forum, I think we will see production EVs powered by solid state batteries in less than 10 years.

    However, I’ll be surprised if Toyota is the first to make a BEV using that tech. Not merely because Toyota has been dragging its feet about producing a BEV, but also because with so many companies and university research teams feverishly working to produce next-generation li-ion batteries, the odds are pretty low that any given one of them will be the first to commercialize the tech.

    1. Dave86 says:

      Looks like Toyota is “scheduling invention”. And the problem with scheduling invention is that there are problems still to be solved, and it’s very difficult if not impossible to predict exactly when those problems will be solved.

      We’ve seen this very same thing – the problem of “scheduling invention” – with hydrogen fuel cells. The hydrogen proponents have been telling us “another 5 years” for the last 15 to 20 years. The issue they’re having is that there are still necessary improvements (& cost reductions) to made with the technology.

      It’s interesting to note that Toyota, a company that has been focused on hydrogen fuel cells and lagging in EV product introductions, is now claiming to have technology that will put them ahead of the rest of the industry in a few years. It’s difficult to believe they actually have anything.

      1. mzs.112000 says:

        Hydrogen fool-cells are IMO a scam from the oil companies.
        It takes $500,000 to build ONE hydrogen fueling station, then it needs to be resupplied for the rest of it’s service life, and guess what, where does all that hydrogen come from right now? Natural Gas, which is a fossil-fuel.

        EV charging stations are comparatively cheap, only $100,000 in installation costs for a 50kW fast charger, and about $60,000 for a 24kW fast charger, both has about a $800 per year maintenance cost, plus cost of electricity, so for the cost of ONE hydrogen station, we could put in 5 fast charging stations for EV’s.

        OH, another advantage to EV’s, they can be fueled at home, if you try to fuel a hydrogen fuel cell car at home, your house will explode.

      2. Alex Clabburn says:

        You are probably right but Toyota have been working on this since at least 2008 initially focusing on the material science inventions that were needed first. There is a chance they could be further along the path than the skeptics think and if they decide to push the button and deploy this en mass it could change everything very quickly. I guess time will tell.

  12. ffbj says:

    time spent for reloading an ICE vehicle.

    Shouldn’t that be refilling? Why would I reload my ICE. Maybe my Magnum.

    1. Mike I. says:

      It’s a translation thing. Many languages literally translate their word phrase for EV charging to “loading”.

      1. scott franco says:

        Cargar is both charging and loading in Spanish. In french is it charger, also dual meaning.

  13. I3 says:

    If they have a Solid State Battery, and their boss is already testing a electric car then why 2022 5 years

    1. john1701a says:

      Why aren’t all computer hard-drives now solid-state?

      1. scott franco says:

        Because you are cheap and haven’t bought one.

  14. Alaa says:

    Juts like VW

  15. Damocles Axe says:

    Oh please God – don’t allow editors to publish ‘new battery’ articles unless there are actual cars on the road using them.

    That would eliminate 99% of all ‘new battery’ noise we hear every. single. day…

  16. Jake Brake says:

    Here is a tip… if an oem actually has a ground breaking product in the pipeline they dont tell everyone and ruin their competitive advantage. The same logic can be applied to groundbreaking announcements 5 years early…

  17. Zbig says:

    Concept vehicle here, great new technology there but nothing to show for real (and probably never will be). The truth is, only Tesla charges forward in electric vehicle market and creates reality other producers must (though very unwillingly) recognize. Thumbs up, Elon.

  18. Don says:

    I’m 100% sure that there will be some better batteries in 2030, bra bra bra …

  19. James says:

    True that talk is cheap.

    Solid state batteries seem the same as SSDs in computers. Desirable? Yes. Faster? Yes. Better? Mostly but for reliability development delays.

    Hard drives still are cheaper to make thus we plow on with inferior tech.

    I’ve been hearing about affordable OLED TV’s for years, but major TV manufacturers have tooling and procurement networks in place for LED LCDs and they are “good enough” and provide HD images. There eventually will be a mass exodus to SSDs and OLED screens as frontrunners like LG force their competitors to compete.

    Solid state batteries seem to be the future. Liquid electrolyte Li Ion batteries are good enough. With carmakers timid to shake up the market with mass production levels of EVs and plugins, how long do you suppose solid state state will take? My guess – 15 years minimum. So like SSDs and OLED, fun to dream about, but years and years away.

    Look to one breakout company, most likely Tesla, to breach the market, and others to follow. I see liquid electrolytes being with us for a long time. Most likely in ten years finding their way into $15,000 cars with solid state reaching the higher end of the market.

    1. Robert Middleswarth says:

      SSD are taking over as we speak. Outside of storage servers, almost all servers come with SSD. Same is true for laptop and tablet. It isn’t until you get to low-end desktop and storage servers they Magnetic storage is still heavily used. At this point, it is just a matter of time for SSD to take over the market.
