Smartphones have a nasty habit of dying on us at the most inconvenient moment; we try to revive it with latest gadgets like battery packs and wireless chargers but we still have to wait for at least a few hours to get them fully charged. This waiting time of hours may soon to changing to a couple of seconds thanks to an innovation from Eesha Khare, a 18-year-old Indian-American girl from Saratoga, California. Her supercapacitor is a tiny device that can hold a lot of energy and can be fitted inside a cellphone battery to charge it almost instantly.


At present she is using it to power LEDs but she is sure that the super-capacitor could soon find its way to cell phones and other gadgets. As compared to the conventional batteries that last for 1000 charge-discharge cycles her super-capacitor can last for 10000 charge-discharge cycles. When asked about her inspiration behind this invention she replied "My cellphone battery always dies,”. Her interest in nanochemistry helped her to develop this device which she claims is flexible enough to be used in rollup displays and clothes. Her invention has managed even to gain attention from Google who have contacted her to see how she plans to plans to use it to improve her technology so that it can be used in cellphones. Eesha was awarded a $50,000 prize and the Young Scientist Award by the Intel Foundation during the Intel International Science and Engineering Fair, conducted last week in Phoenix, Arizona.
