Student develops a capacitor that could charge a cell phone in 30 seconds
The supercapacitor she has developed may hold the key to recharge a cell phone battery in less than a minute. Amazingly, even at this fledgling stage, the technology already can handle 10,000 charge/re-charge cycles which is 10-times better than most modern day batteries.
Khare’s invention is also solid-state which means good things for the need of new technology to be environmentally responsible. So far, the supercapacitor has been used to power LEDs and will also be able to be used in flexible environments like fabrics and bendable displays. The project is titled “Design and Synthesis of Hydrogenated TiO2-Polyaniline Nanorods for Flexible High-Performance Supercapacitors.”
She has already had big players like Google reach out to her, though Khare is not revealing the nature of any discussions. Obviously, the applications for this technology will have the potential to touch everything that uses rechargeable batteries, from cell phones to electric cars or razors.

That means people using smartphones wouldn't have to complain about their battery lives anymore!

A much needed invention. congrats and thank to the young scientist! her project deserves attention!

Another news about some Indian inventing something new in US. Damn Indian Govt wake up..

First of all, Indian people should start to respect their woman, cause they are suffering much undue hardship. I say, good luck to her and get out of India.

I neither can agree with you, nor deny what you said. It's like.. you see both extremities here.
Things have really improved and it's not at all like what people in other countries think. Media nowdays draw gruesome pictures and people believe everything .__.

No matter how much India progresses, it will always be light years behind the US (considering rate of advancement in technology). In my college, the research kits are of 1996 and computers are Win 98 with 64Mb RAM fml. If you want a better career, go to the US.

Hey kdealltheway, did you even bother to read the article? She's an American living in the U.S., not in India.
44. kdealltheway (Posts: 79; Member since: 21 Oct 2012)
Yeah, I've bothered. I was responding to eisenbricher, not directly to an article.

And so-called geeks on PA inventing nothing while compalining about every innovation out there.

Wow thats amazing! Nows lets just hope and pray that we see this in our cell phones and other electronics within 2 years.

Really? They didn't even post one of my tip.

18 years old and making a difference, unlike you trolling and being irrelevant to the world.

God I hope she can patent that, I have a feeling since Intel sponsored the event, they take the patent. Hope I'm wrong.
11. ZeroCide (Posts: 678; Member since: 09 Jan 2013)
Intel may file the patent but i'm sure that she will be allowed to put her name on the patent and she will recieve some of the patent income.

I can see this being an excuse for manufacturers using smaller batteries.

she is innovative.this is true innovation
15. GhostBear (Posts: 18; Member since: 01 Feb 2013)
I wonder what levels of Ampere Hours it stores.
18. xperiaDROID (Posts: 4835; Member since: 08 Mar 2013)
Wow! That's awesome! Now that's what I call INNOVATION!

Who are thumbing you down???you have nothing against anyone...

I thought the capacitor would be replacing the battery not being used to "recharge a cell phone battery" but i could be wrong.
21. Shrihari (Posts: 79; Member since: 29 Jan 2013)
please patent that first else apple is gonna include it it iphone 6 and say its their invention...

supercapacitors are nothing new, they dont have near the energy density of batteries.
thats the catch... a battery that only lasts 4 hours but charges in 30 seconds.

Well I do study in Physics, nano-electronics and this article is as always, incomplete about the technology and about the real usage of this discovery witch is normal because this is not a specialized site.
By the way, I think this trick was discovered by this girl a while ago (or maybe a similar technique found by somebody else) because I remind that I read something like this in a paper magazine some weeks back.

Congrats to Eesha on her ground breaking discovery. Hopefully some of these major players can start funding her research to expedite the development and testing process, so that we can see this new technology being applied to cell phone batteries within the next 2 yrs.

And it will all be ready in about a decade
30. krustyclown841 (Posts: 1; Member since: 20 May 2013)
Wow hopefully with this we can charge future electric vehicles as quickly as filling up a car with gas. being at a supercharging station for 30 minutes or more is not practical for long trips...

this reminds me toyota TS030 Le Mans car with supercapacitor for energy recovery system.

even if she invented a battery that lasts a 1000 years she's still ugly!

Congrats to her, she created something amazing that is gonna make consumer life even better
