Teen invents tech for 20-sec battery charge The supercapacitor is said to have a life of 10,000 cycles, about 10 times that of a normal mobile phone battery.

A Californian teenager has caused a stir in the global electronics industry by inventing a ‘supercapacitor'-based device that has the potential to fully charge a mobile phone battery within 20 seconds.

Esha Khare this week bagged a $50,000 prize for her invention at the Intel International Science and Engineering Fair, in Phoenix, Arizona. The 18-year-old employed her niche knowledge of nanochemistry to develop the component, which she used to power LEDs.

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

The Saratoga, California resident told media that she had been inspired to design the device because of frustration with the slow charge rate of her mobile phone. The supercapacitor is said to have a life of 10,000 cycles, from charge to recharge, which is approximately 10 times that of a normal mobile phone battery.

Khare is set to attend Harvard and has vowed to "set the world on fire". We assume she is not referring to possible malfunctions in her invention.
