18-year-old Indian-American girl has invented a super-capacitor device that
could potentially charge a cellphone in less than 20 seconds.
Eesha Khare from Saratoga in 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.
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, NBC News reported.
Ms Khare has been awarded USD 50,000 for developing the tiny device. She has
also attracted the attention of tech giant Google for her potentially
According to the teenager, her device can last for 10,000 charge-recharge
cycles, compared to 1,000 cycles for conventional rechargeable batteries.
"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 - "really
working at the nanoscale to make significant advances in many different fields."
The gadget has, so far, only been tested on an LED light, but the good news is
that it has a good chance of working successfully in other devices, like mobile
phones, the report said.
Ms Khare sees it fitting inside cellphones and the other portable electronic
devices proliferating in today's world.
"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," she added.
