CES 2015: Israeli Firm StoreDot Promises Electric Car Battery That Will Recharge in 3 Minutes

In today’s modern world, there’s massive commercial reward for battery companies who can produce affordable, lightweight and high energy density battery packs. From smartphones and tablet computers through to electric cars, entire industries rely on continuing evolution of the humble battery pack.

To date, we’ve mainly seen companies focus on energy density and production costs, producing batteries which can store more energy per unit mass than previous generations and cost less to make. But at this year’s Consumer Electronics Show in Las Vegas, one Israeli firm is demonstrating a rapid charge battery technology that can replenish a mobile telephone from empty to full in less time than it takes to boil a kettle.

StoreDot says it has the technology to revolutionise the plug-in market.

And it says it’s about to bring that same technology to the electric car world too, resulting in electric cars that can be recharged from empty to full in the same time it takes a gasoline car to fill up with premium.

Enter StoreDot, a company which has raised more than $42 million in funding for its bio-organic, self-assembled ‘nanodot’ technology. According to its official website — which we’ll admit is full of lots of words but light on explanation — nanodots are made of “the first bio-organic nano crystal ever discovered” measuring just 2 nanometers in length.

“Nanodots are bio-organic peptide molecules that change the rules of mobile device capabilities,” the site helpfully continues. And while we love science, we think it might be easier to think of them as tiny, superheroes of the nanotechnology revolution. That’s because unlike other nanotechnology solutions, nanodots are non-toxic, made from abundant biological materials and if constructed in the correct way, have an amazing array of possible applications.

The company has raised more than $42 million in funding to date.

In addition to being very uniform in their shape and size, nanodots have the ability to naturally emit red, green or blue light, making them perfect for use in next-generation displays. But they also happen to transfer data faster than traditional silicon-based electronics, can easily cross the brain-blood barrier in the human body to allow drugs to target specific parts of the brain with unparalleled precision, and can dramatically improve the conductivity and energy storage capabilities of electrodes.

If you’ve heard of StoreDot before, you’ll know that last year the company demonstrated its technology by retrofitting a standard smartphone with a specially-designed nanodot battery pack and recharging said battery pack from empty to full in 30 seconds.

But while the demonstration was impressive, it relied on a bulky specially-designed harness which made the phone unwieldy to use.

This year, StoreDot’s CES demonstration showcased a brand-new generation of nanodot battery pack, one which is small enough to fit inside the case of a conventional smartphone and can store as much energy as a stock battery pack.

The firm’s CEO Doron Myersdorf told the BBC this week that the battery itself was comprised of a mesh-like structure consisting of an undisclosed polymer and metal oxide laced with nanodots,

“It acts on one hand like a supercapacitor that charges very fast, and on the other hand like a lithium-ion battery,” he told the BBC in an interview ahead of the CES show. “So this combination is a new generation of battery.”

“It allows us to charge very fast, moving ions from an anode to a cathode at a speed that was not possible before we had these materials,” he continued.

For now, the firm has only built smartphone-sized battery packs for demonstration purposes. But in a year’s time Myersdorf says, the company will demonstrate a full-size electric car battery pack that can recharge itself in three minutes. Claiming interest from several unnamed electric automakers, the firm is confident its technology could change the plug-in world forever.

We’ll admit the technology and the dream behind it is appealing. If plug-in cars could be recharged in minutes rather than hours, it could finally swing plug-in vehicles into the mainstream market as truly competitive alternatives to gasoline and diesel-powered vehicles.

But as with any impressive technology demonstration, the hardest part is taking a small-scale academic possibility and making it a viable, reproducible, economically-sustainable reality.

And that’s a tough, tough task.

    That is very impressive technology.nnOf course it would be better still if it was truly a ” battery pack that can recharge itself”. Perpetual motion anyone 🙂

      Model S 85 = 1 megawatt plus for 5 minutes straight.

      I was thinking the exact same. 480kW is simply not realistic without a huge battery array behind it to cover the peak.

  • Chris Brooks

    +johnCBriggs I thought that and think of the connectors. Even for a phone we will need to bigger cables and connectors but a Car sized battery is a whole new issue.nnnOkay so 3 minutes is a bit much unless you can have batteries at the charge points to provide the power. These batteries can then be slower charged at today’s rates.

  • CDspeed

    Sounds great, I’d like to see a small company revolutionize batteries, just like Tesla has shown how an electric powertrain can revolutionize automotive design. We still can’t say which battery will bring the revolution, but I’m sure we have already read about it.

  • BEP

    JB Straubel is not impressed (I guess).

    • Espen Hugaas Andersen

      He probably is, I certainly am.nnThere are two battery technology challenges that are relevant today. Those are energy density and cost. Storedot doesn’t adress either one, as far as I can tell, and it is therefore irrelevant.nnThere are lots of battery chemistries that can be charged in a few minutes. They are equally irrelevant for mass-market EVs because they are expensive and have terrible energy density. (Well, the Toshiba SCiB (6 minutes 0-80%) have found their way into a low-range version of the i-MiEV, but that’s not what we will be driving in 10 years.)
