Eesha Khare's Super-Capacitor Devices

Eesha Khare, 18, an Indian American has been awarded the Young Scientist Award. She has successfully designed, synthesized and characterized a novel nanorod electrode super-capacitor with increased energy density while retaining power density and long cycle life.

This work is an important initial step in introducing this new electrode material in super-capacitors to replace conventional batteries in flexible electronic devices.

In simple terms, she has invented something that will allow you to recharge your mobile within 20-30 seconds. Now, compare that to the hours that are required to charge the batteries currently being used in your cell-phones!

The super-capacitor is a tiny device that can hold a lot of energy in a tiny space. It charges very fast and can hold the charge for a long time.

This super-capacitor has a great future, especially in today's age where small smart devices are making great in-roads in our day-to-day life. So many times we are left stranded when the batteries in our mobile phones run out of power and require hours to recharge.

According to the young scientist, her devices can be used for 100000 charge-recharge cycles compared to about 1000 cycles for conventional batteries. She says that it also demonstrates a much higher cycle life compared to batteries.
