She won the $50,000 Intel Foundation Young Scientist Award

A high school student from California has created a way to charge cell phones completely in just 20-30 seconds. 

Eesha Khare, 18, of Saratoga, California, recently won the $50,000 Intel Foundation Young Scientist Award for her fast-charging device. 

The device uses an improved supercapacitor that can store a lot of energy into a small space using a nanorod electrode. It is capable of 10,000 charge-recharge cycles and can fully charge a cell phone in 20-30 seconds. 

Traditional chargers typically take hours to achieve a full charge, and are capable of only 1,000 cycles for rechargeable batteries.


Khare said her supercapacitor has been used to power an LED, and sees her invention being placed in cell phones in the future.

"It is also flexible, so it can be used in rollup displays and clothing and fabric," Khare said. "It has a lot of different applications and advantages over batteries in that sense."

This definitely isn't the first time a high school student has come up with a brilliant invention in recent years. Just last year, 15-year-old Jack Andraka invented a new pancreatic cancer test that earned him the $75,000 prize from another Intel-sponsored fair.

She's 18. Why don't you go back in time to when you were 18 and create a supercapacitor? Jesus Christ, lmao. What is with you people??


You mean go back to when I was 18, have mommy and/or daddy get me into a lab and convince the professor to let me take credit for some of their work so I can win a $50K prize and pretend I'm a genius?

She didn't "create" a supercapacitor, BTW. She claimed she did. She has nothing FUNCTIONAL to show, only claims and some cut-n-pastes from wikipedia printed out on some poster board.

What problem are you solving by making up all this stuff? Is this situation really important enough for you to fabricate entire narratives about what actually happened? Does it make you feel better about your life or something?

I'm genuinely curious. If it does make you feel better I can be a lot more supportive of it; I'm a firm believer in peace of mind. If falsities about this woman's achievements are helpful to you, I believe are arguments to be made in your favor.

Karim,

If you actually bothered to dig more details into this, you will everyone else's point. To everyone else, you are the fool. I'm guessing you didn't bother to even read the links.

This coming from the dude who missed that the point of the whole thing was to replace batteries. Understandably, you were sidetracked by Intels claim that her device "fits inside cellphone batteries." But the problem is you lacked the reading comprehension to see past that and understand that she herself was clearly targetting a battery replacement mechanism, and are subsequently counseling me on reading comprehension.

I read the links. Everyone's point is that she was given this award because she's a girl. Because "everyone" is an idiot.

You didn't even bother to read her abstract and result.

Her result of 20.1 wh/kg is nowhere close to replacing batteries that are already mainstream today. The batteries mainstream today are also lab tested and developed in decades past.

In conclusion. Her "invention" failed as a buffer supercapacitor to charge battiers.
Her "invention" failed as a battery replacement

To give you a reference. If that SC was the same weight as a battery and working with same efficiency as the lab experiment then:
Your phone will only last 2 hrs at best.
It would cost more than the Lithium Ion battery.

Her conclusion claimed it was successful compared to mainstream supercapacitors. Mainstream supercapacitors only have the energy storage of 5% of lithium ion batteries. Doubling the capacity only make it 10%. That is not successful to me.

She never claimed to replace batteries. She said her design surpassed the typical energy density of supercapacitors. It's a step toward replacing batteries. Did it or didn't it surpass the typical energy density?

I'm really sorry that this teenager didn't solve the battery problem. lmfao. For $50,000.

You people are insane.

Thanks for clarifying her experiment didn't do better than what's commercially available. It did not solve the problem of density or cost. EDLC has been around for a while.

More like a step in place.

I'm "genuinely curious" why you have so much interest in defending this girl. Everyone else here is right. She is getting credit for some BS "design" that anyone can just talk about. Every post you have made (@karimtemple) just looks ignorant. You started calling people sexist out of nowhere and you have failed to bring anything to this comment section. It is not sexist to say that this girl shouldn't have won. It would be sexist to say that a girl shouldn't have won. If you can't see the difference in that then it is clear why you are not understanding people rejection to this. I'm going to lay this out really easy for you:

This girl did not invent capacitors, that happened way back in the mid 1700's if I'm not mistaking. This girl did not invent super caps. This girl has not achieved some new level of super caps. She has merely said that capacitors can charge batteries to a team of PhD researchers who already knew this. Then she said, I want $50k so we need to make a capacitor. Then the researches probably spent about 30 min if they are skilled in electronics and layered together a capacitor from materials they had in the lab students pay for. She took this cap and put her name on it and sent it to intel. Then out of all the great designs I'm sure they got, we get a report about this girl. That is irritating to us. So we have all posted pointing out how poorly this contest was judged. Then you came in, with no background in electronics and started making erratic claims that we are all sexist because we don't this is valid in the slightest.
No we are not "getting off" on this. No we don't feel better for putting others down. We feel better letting the people who lost know that not everyone in the world thinks this is all that legitimate of a competition if the "winner" "won" by "designing" something that has already been around, and failing to even charge a cell phone with it. She just knows people like cell phones and hate charging and put those to buzz words together in a paper that caught intel PR teams attention.

I typically recharge my R/C LI-PO packs (5000mah) in 5-10 minutes (the maximum my charger puts out is 12v 25amps which roughly comes out to 8.4v 35amps) and that includes balancing overhead.

Single cell packs (~3.7v) charge more efficiently because you don't need to keep cell voltage "balanced."

If a charger can output enough power there is cell chemistry that can absorbed it. Obviously nothing charges faster than a capacitor, lasts as long, or discharges as fast, but I have personally seen a truck jump-started with a 3-cell helicopter battery that could output 50C (or 50x its amperage) so figure 5A x 50x = 12.8v @ 250A, or just enough to turn over a typical starter motor assuming the existing battery still has some juice.

LiPO is great but it has it's limitations (outlined on Wikipedia), which is why it's not used in cell phones. They are very popular in the R/C industry.
