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.
