Electric Car Battery With 300 Mile Range, 5 Minute Charging Time. It’s Possible, Says Israeli Company

 

People who build conventional cars think their business model is safe because who would drive an electric car that takes an hour or more to recharge when you could drive a car with an internal combustion engine and never spend more than five minutes filling the tank? Range anxiety is seen by many as the number one reason people don’t want to buy an electric car, but it really is about convenience.

Those who advocate for hydrogen fuel cell powered cars use the same argument — it only takes 10 minutes of so to refuel with hydrogen. What sort of idiot would waste an hour or more charging a battery when filling a hydrogen storage tank takes so little time?

Both groups may be about to have their worlds turned upside down by StoreDot, an Israeli company that claims it has new a new battery that can go three hundred miles on a charge and then be replenished in only five minutes. If true, the electric car revolution just took a giant leap forward.

First, a word of caution. The news is filled with stunning advances in battery technology that are coming from laboratories around the world. Billions is being spent on battery research every year. People like John Goodenough have devoted their entire lives to finding better batteries.

StoreDot demonstrated its new battery to the public at the CUBE Tech Fair in Berlin last week but mostly what the company has done is create a very cool video that shows how its new flash battery works. According to the company, it uses “proprietary organic compounds” and no graphite. It claims the electrolyte is non-flammable.

“Fast Charging is the critical missing link needed to make electric vehicles ubiquitous. The currently available battery technology dictates long charging times which makes the EV form of transportation inadequate for the public at large,” says StoreDot co-founder and CEO Dr. Doron Myersdorf. “We’re exploring options with a few strategic partners in the auto space to help us boost the production process in Asia and reach mass production as soon as possible.”

The possibilities are mind boggling. Tesla’s Supercharger network would be rendered obsolete overnight. Wireless charging strategies would cease to be relevant. Electric cars would be as convenient to use as conventional cars. The switch to electric cars would be moved forward by a decade of more, with all that implies for lowering carbon emissions and ending the hegemony of the fossil fuel industry. For those reasons alone, let’s hope the StoreDot technology is more than just hype.

    20 to 1 odds, this is either pure vapourware or it will take 15 years before it can be mass produced, then safely and reliably integrated into actual vehicles.

    If even remotely true, it would more than revolutionary.

    • Steve Hanley

      My inbox gets 6 or 7 “amazing battery breakthrough” announcements a month. All of them sound promising. So far? Nada.

      Will this be the one? Your guess is as good as mine but it is a tiny bit exciting to think, “Maybe this is really real.”

      Still, your skepticism is amply justified. “We’ll see,” said the Zen master.

    • bioburner

      Agreed. A car that can go 300 miles on a charge will need at least 100 KWH battery so a 5 minute recharge will require an average power level of something like 1200 KW. I’m thinking the Tesla super chargers will be ok for a long time.

      • When Musk was asked if the new generation of the supercharger will be faster than the 400kW proposed by an other group he refered to the 400kW proposal as “toy” chargers.

        I wouldn’t be surprised if the next gen Tesla supercharger would be something like 1MW.

    “IF”,

    A typical BEV gets 3miles/kWh,
    And this new battery tech can support 300 miles before recharging is necessary, that equates to a 100kwh battery.
    A 5 minute recharge equates to 1200 kw load, (60 min/hr/5 minutes x 100 kWh)?
    The physical cable to handle this power is huge. What voltage does this new tech run on?

    • Epicurus

      Thanks for this info. I assume I am not the only one who doesn’t know enough about electricity.

    • Oollyoumn

      To determine the cable size you would need voltage and current not kW. For example, at 12kv you need 100a to get 1200kw. Also, my BEV may not be typical, but my trip computer shows 4.3 mile/kWh over the last about 1 year. I think the Ioniq should do even better.

      • roseland67

        Thus,
        the last sentence in my post.
        “What is the voltage this tech runs on”.
        Once voltage and power requirements are determined, current draw is easily caculated.

  • Epicurus

    Correct me if I am wrong, but right now you get an 80% charge in 30 minutes at a Tesla supercharger (are competing fast chargers as fast?). If there were a nice restaurant with clean restrooms serving good tea, coffee and other beverages and tasty snacks, it would be easy to get accustomed to a nice 30 minute break every 250-300 miles. This is a huge potential market for, I hate to say it, Starbucks, or hopefully some restaurant offering tastier food. At what Starbucks charges for coffee, they could give away the electricity for non-Tesla EVs.

    • roseland67

      Tesla fast chargers aware built exclusively for Tesla vehicles and operate at very high voltages.
      These voltages are NOT available to the general public.

      • Epicurus

        There are the DC fast chargers too.

  • Sheldor

    Wow?
    Range and charge time?

    Try size and cost.

    • bioburner

      All 4 parameters play into it. As well as durability. Calling people Morons does not cast a good reflection on your self.

      • kevin mccune

        I don’t think He meant to be harsh, it seems He is telling us ,things are actually fairly good now , if we want to take advantage of them.The 5 minute recharge blows my mind, you got to download energy pretty fast to be to do that, perhaps its some sort of a very energetic high vibration download , that defies normal logic and parameters or perhaps its just another battery swap idea. A million watts is a lot of electricity to deal with.

  • Frank

    Great. Show it to me.

  • Aren Anderton

    Nothing very unique or special about this. Many current gen hobby batteries are rated for 15c charge rate, which equates to a 4 minute change. This is nothing but saying that you could get enough of those to run a car and charge them at 12c. However, cost and power to charge would be astronomical, and battery longevity would be pathetic. What Tesla has done will not be rendered obsolete overnight.

    Everyone who is making electric cars is working towards faster charge times. This company is just riding some hype of what is currently technically possible, not currently bound by things like reality when making hype videos. A 12c charge on 100kWh is 1.2 Megawatts. 4 parking spaces would need to be able to intermittently deliver 5 Megawatts. Let’s see you on that on every corner. Or even anywhere.

    • roseland67

      I think the vehicle range, charge rates and times are fine now.
      Any significant range improvement will from improved battery chemistry,
      (sodium, aluminum etc),
      NOT, better charging tech.

      • Aren Anderton

        By definition, improved charging tech will not improve range.

        I think charging speed is a good thing to improve, but battery longevity is more important. So you must find a careful balance that is dictated by the chemistry.

        Range on electric cars is pretty good as it sits. I use a Chevy bolt with a 38 or so mile range, and it completes almost every day on electric. On a longer range car, most of the range isn’t used most of the time. It’s just when you need to travel that it becomes an issue. So, charging tech might be a better solution than longer ranges.

        • roseland67

          Aren,
          Agreed,
          Charging speed still equates to larger cables as the more power you put thru a cable the bigger the cable has to be.

  • Michael Anthony

    I completely understand why the public has become skeptical when it comes to this topic. No one wants to be the early adopter after forking over such a large sum for the investment. But people should keep in mind how far we’ve come.

    Remember the first wave of the Tesla roadster? We drooled over that little go-cart. Took a little while to charge eh? As battery & charge tech advances, we will all benefit in the long run.

    So, take that Tesla, drive the hell out of it! Just be sure you pack a light snack and some magazines to pass the time while recharging!

    • roseland67

      The overwhelming majority of us will rarely if ever use a supercharger.
      We will drive our electric vehicles to work, park them in our garage at night, plug them into either 115 or 230 Volt outlet and the charge they get over that 8-10 hour period of sleeping will be more than enough energy for the following days use.
      Range anxiety, as I expected, is a non issue and as we all get used to driving electric cars, it will be akin to how often we think about running out of gas.

      • Epicurus

        Right. Why is the decision to buy an EV revolving around the one cross-country trip one dreams of taking but rarely gets around to? It’s ridiculous. If people are that obsessed, let them get a PHEV with a decent range like the Volt.

        • roseland67

          agreed,
          Over time, I expect most of us will have an electric vehicle AND and ICE

  • That’s an exaggeration, Michael. You don’t need a snack or magazines as most of the Superchargers I’ve visited in the Northeast are near Whole Foods or other markets or at service areas with plenty of food service. On my annual trip to Montreal, I stop twice, and 30 minutes gets you another 100 miles or so to reach the next Supercharger. Think of it as a relaxed bathroom break.
