It’s a tiny a gadget that fits inside cell phone batteries, and allows them to fully charge within 20- to 30 seconds. Typically, it takes several hours to get a full charge.
Khare demoed her “super-capacitor” last Friday at the Intel International Science and Engineering Fair. The 18-year-old genius from Saratoga, Calif. walked away with a $50,000 prize for the energy storage device that can last for 10,000 charge cycles. Compare that to standard batteries, which are typically only good for 1,000 cycles.
During the demo, Khare showed off how it could power a LED light. But in the future, the device could easily be used in roll-up phones or maybe even car batteries.
“With this money I will be able to pay for my college and also work on making scientific advancements,” Khare told the audience after receiving the prize.
