<p>An 18-year-old Indian-American girl has invented a super-capacitor device that could potentially charge a cellphone in less than 20 seconds.<br /><br /></p>.<p>Eesha Khare from Saratoga, California, was awarded the Young Scientist Award by the Intel Foundation for developing a tiny device that fits inside mobile phone batteries and charges them in 20-30 seconds. <br /><br />The so-called super-capacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds the charge for a long time, NBC News reported.<br /><br />Khare has been awarded $ 50,000 for developing the device. She has also attracted the attention of tech giant Google for her potentially revolutionary invention.<br /><br />According to Khare, the device lasts for 10,000 charge-recharge cycles as against 1,000 cycles for conventional rechargeable batteries.<br /><br />“My cellphone battery always dies,” she said when asked about what inspired her to work on the energy-storage technology. Super-capacitors allowed her to focus on her interest in nanochemistry and “really work at the nanoscale to make significant advances in many different fields.”<br /><br />The gadget has so far only been tested on an light-emitting diode (LED) light, but the good news is that there are ample chances of it working successfully in other devices like mobile phones, the report said. <br /><br />Khare sees it fitting <br /><br />inside cellphones and other portable electronic devices. “It is also flexible, so it can be used in roll-up displays and clothing and fabric. It has a lot of different applications and advantages over batteries in that sense,” Khare added.</p>
