A California teen has invented a super-capacitor that could lead a phone charge to 20- to 30-second.
Super-capacitors are energy-storage devices that have a long cycle life. It stores a lot of energy per unit volume. Sounds dandy, right? Not quite. The devices store less energy than batteries because they have limited use.
“The super-capacitor I have uses a special nanostructure, which permits for a lot higher energy per unit volume,” In a last week’s video interview Khare said Intel International Science and Engineering Fair in Phoenix. The largest science fair in the world brought together 1,600 high-school finalists, who competed for more than $4 million in awards.
Khare’s demonstrated and make a test with an LED light.
“After 20 seconds of my super-capacitor charging, I was able to light an LED device,” she said. “LED light was my signal, it shows what I’m doing, and this is truly applicable to the real world.”
Within 20 to 30 seconds phone could be fully charged. Khare’s tiny device fits inside cell-phone batteries. The advance feature in energy storage could also be applied to laptops and electric vehicles, and some other devices.
Khare won a $50,000 Intel Foundation Young Scientist Award (pictured above, far left) in Intel’s competition. After receiving the award, Khare said she wants to “just keep making a lot of scientific advancements.”
