An 18-year-old Indian-American girl has invented a super-capacitor device that could potentially charge your cellphone in less than 20 seconds.
Eesha Khare, from Saratoga, California, was awarded the Young Scientist Award by the Intel Foundation after developing the tiny device that fits inside mobile phone batteries, that could allow them to charge within 20-30 seconds.
According to Khare, her device can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries.The so-called super-capacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds its charge for a long time
