High School Student Creates Tiny Supercapacitor for Rapid Device Charging

One day, your mobile phone could recharge in as little as 20 seconds, thanks to the work of a very talented high school student.

We’re all tired of having dead batteries in our mobile devices that take hours to fully charge again, so innovations in small-scale energy storage could radically change the way we build, use, and charge our gadgets.

18 year old Eesha Khare, of Saratoga, California, may hold one of the keys to doing so, and now, thanks to the Intel Foundation, she’s $50,000 closer to bringing her invention to the market.

Khare has developed a tiny supercapacitor that fits inside mobile phone batteries, enabling extremely rapid recharging of the devices (20-30 seconds), while also increasing the number of charge cycles possible by a factor of 10 (when compared to conventional batteries). Her device is also capable of holding a charge for a long time, which could have huge implications in other energy storage solutions, such as automobile batteries.

“It is also flexible, so it can be used in rollup displays and clothing and fabric. It has a lot of different applications and advantages over batteries in that sense.” – Khare

Khare is one of the winners of the Intel International Science and Engineering Fair, and was awarded an Intel Foundation Young Scientist Award of $50,000.
