“Struggling to get through the day without charging up the smartphone?” Amir Mizroch reports for The Wall Street Journal.
“StoreDot Ltd., a Tel-Aviv based start-up, says it hopes to at least make the charging process faster–unveiling Monday a prototype charger that promises to take you battery from a tiny sliver of red to 100%, all in about 30 seconds,” Mizroch reports. “StoreDot was born out of the nanotechnology department at Tel Aviv University and developed its prototype for Samsung’s Galaxy 4. It unveiled the device at Microsoft’s Think Next conference in Tel Aviv. StoreDot says it plans to make chargers for other smartphones, too.”

Didn’t some high school girl in CA invent that at a science fair over a year ago???
Can you say patent infringement?
If she patented it, and if this is the same technology… However, in the U.S. You can probably find some idiot to allow you to patent “charge cell phone in less than 30 seconds” without providing any additional detail.
You don’t understand patents.
You don ‘t get sarcasm.
This technique exploits nanotechnology. I would be very surprised if a high school girl were synthesising peptides.
There are multiple ways of permitting fast charging batteries, this looks to be an original approach, but there are very few details published at the moment, so it’s hard to know if it’s a promising technology, or just another hyped up concept with a huge downside. My hunch is that it’s well worth further consideration.
If this technology works well and is scalable, I would expect that manufacturers of electric cars will be extremely interested in having a battery that can be recharged so quickly.
For now all fast-charging technologies have caused fast deterioration of maximum full-charge capacity of battery. If those developers somehow were able to avoid this issue (what I highly doubt), then it would be significant.
Here is the story on the California student battery charger invention.

Thx for digging it up.
There just has to be a drawback to this. Exploding batteries perhaps, batteries with a quarter of the life, or a charger the size of a fusion reactor, yup, you just know this is just too good to be true, rather like those advanced chips in the 90s that Apple was reportedly on the brink of using that were supposedly massively faster than existing ones, were delayed for years and actually in reality offered no more than a 5% increase despite all the claims.
However despite my cynicism if true this development will transform recharging.
I want one.
Awesome. Jut give me sometime to build a portable, collapsable Blast Proof Container. Just in case right? 😉
Talk about a brick of a phone… Does that contraption become the battery and have to stay in place? If so, no thanks.
And it’s only adds 2 inches to the phone’s original thickness! Also makes for a nice handle for holding the phone up to your ear. Just needs a leather holster to hang the phone (and the double-ended male power cord) from your belt.
There’s talk about multicore processors. This seems to be, multi cell batteries. There needs to be a lot of them, like 1000’s of them. This is where I can see nano tech coming into play. That brick of a battery attached to the phone is big for a reason, because it probably is made up of many many cells. Give this tech another 5 to 10 years to develop, I think.
Since batteries provide energy by chemical reaction, which takes time to reverse, if you could reverse the chemical reaction all at once, by reducing the size of the reserve, and joining many of them in parallel and series. I think it would be like filling a gas tank.
If you use this process on a car, it would have to have millions of cells, which could be charged in 5 minutes, at a power (petrol) station. I am sure Tesla and Apple are already working on this. And that’s why StoreDot is working with Samsung.
Let’s hope and see what comes out of it. If true and could be applied to cars, then this it the killer app for plug-in electric cars.
And they had to use a samsung phone for the demo…figures.
Well… it has a removable battery
Don’t name it M5.
Daystrom out.
We’re going to need a bigger screen. (To hide the growth on the back.)
To charge an iPhone’s 1.2 amp-hour battery in 1/2 minute would require a charging current of 150 amps or more. Yes, 150 AMPS, for 30 seconds. A Li-Ion battery of that size would explode in 2 seconds at that current.
This article is B.S.
I agree. You don’t get that fast a charge for free. There is a chemical change that takes place in the battery. . . And it’s exothermic. It gives off heat in both charging and discharging. Too fast and the heat will want to go somewhere fast!
How many times?
Wingsy has it almost right–but the numbers supplied are too low.
Assuming 100% efficiency, a 1.4 amp-hour storage cell of any kind requires 168 amps to charge in 30 seconds. The energy that comes out of the cell has to get in. That also means conductors at least 1 cm in diameter and connectors correspondingly large.
There is no magical nano-technology involved or charger with mysterious pulsing currents. Only faith in the gullibility of the tech press.
Once charged, the nanobattery lasts 10 seconds. Now it all makes sense.
I call bullshit. There’s no way you can charge anything with a video.
