An 18 year old named Eesha Khare has invented a device that can be fully charged in 20 to 30 seconds, which also lasts longer than normal batteries. She did this for an international science fair and took home a $50,000 prize.

If there is one thing that disappoints a lot smartphone users around the world, it’s battery life. We always wish that the phones would not only charge faster but also last longer than they usually do. Eesha Khare, an 18 year old from Saratoga California has taken the issue into her own hands, and has created an energy storage device that can be fully charged in 20-30 seconds.

Eesha took home $50,000 at an international science fair for her new device, dubbed the supercapacitor. Not only does it charge quickly and hold the charge for a long time, it also lasts 10 times longer than normal batteries which last around 1000 charge cycles, that’s 10,000 for the mathematically impaired, which is very impressive.

The 18 year old explained to NBC news that the reason she was inspired to do this was because her cell phone battery always died. She also cited her deep interest in nanochemistry as another reason for wanting to explore it. Eesha remains excited about the future of her device. "It is also flexible, so it can be used in rollup displays and clothing and fabric," Khare added. "It has a lot of different applications and advantages over batteries in that sense."

As long as we have people like Eesha Khare in charge of the next generation of technology, I say our future looks pretty bright.
