Eesha Khare, An 18-year-old Indian-American girl recently invented a portable ‘supercapacitor’ that can fit inside mobile phone batteries and let it charge fully within 20-30 seconds.
Usually, a mobile phone takes around three-four hours to get fully charged. Over years, many mobile phone companies have been working hard on super-capacitors as a potential source of power for their devices. However, the technology has always been limited as they store a lot less power than traditional batteries.
This makes the achievement of Eesha Khare, a hot discussion among tech enthusisats. She is only 18 years old and developed this technology while balancing her school work. She has achieved something which most of the tech enthusiasts couldn’t do though they were cracking their brains over years.
“The super-capacitor I have developed uses a special nanostructure, which allows for a lot greater energy per unit volume,” Khare said. “It can charge very quickly, and it can last for 10,000 cycles, compared to batteries which are only like 1,000 cycles.”
“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 also added.
When asked what inspired to develop such a technology, she said “My cellphone battery always dies,”. This gradually turned her attention to nanotechnology. As batteries are used for storing energy, they suffer from long charging times and short life cycles. Eesha’s project aimed to design and synthesise a supercapacitor with increased energy density while maintaining power density and long life cycle. She visualizes it fitting inside cellphones and the other portable electronic devices of the current scenario.
The gadget has been first tested on an LED light, soon a good news spread out that it can even be used for mobile phones.For developing the device, Eesha received a $50,000 cash prize at Intel Foundation’s Young Scientist Award held in Phoenix, the US.
This event is the world’s largest science fair and attracts more than 1,600 high school finalists from across the globe. She has even captured the the attention of tech giant Google for her revolutionary invention. Eesha Khare has now become a youth icon for most of the U.S teens within a short period of time. Eesha is now busy attending tech seminars and conferences, collecting rewards for her achievement.In the near future you can see how Eesha’s device transform the future of mobile phones.
