Teen’s Invention Could Create 20-Second Phone Charge

Tech manufacturers that boast how fast their devices can juice up might want to listen up: A California teen has developed a super-capacitor that could lead to a 20- to 30-second phone charge. Super-capacitors are energy-storage devices that have a long cycle life, and have the potential to store a lot of energy per unit volume. Sounds dandy, right? Not quite. The devices have limited use because they store less energy than batteries. But Eesha Khare, 18, of Saratoga, Calif. has made quite an advancement with this technology. “The super-capacitor I have developed uses a special nanostructure, which allows for a lot greater energy per unit volume,” Khare said in a video interview at last week’s 2013 Intel International Science and Engineering Fair in Phoenix. The world’s largest science fair brought together 1,600 high-school finalists from all over the world, who competed for more than $4 million in awards.
