People have become so attached to their mobile phones that it’s difficult to imagine our lives before cellular technology. In this day and age a fully-charged mobile phone has become a daily necessity, and waiting an hour for our phones to charge, an inconvenience most of us don’t want to deal with. Once your smartphone is running out of juice, you often have 2 choices: pray your charger is nearby, or pray that somebody with your own phone model has the charger with them. But Eesha Khare, an Indian girl studying high-school in San Jose, California, has developed a gadget (Supercapacitor Phone Charger), which fully charges a mobile phone battery within 20-30 seconds. 18-year-old Eesha Khare was awarded a $50000 prize for creating this magic mobile charger!
Khare demonstrated how it could power an LED light during her demo, however within the future, her device may simply be employed in roll-up phones or even automobile batteries. Khare’s invention led her to become one of the individuals awarded with the Young Scientist Award at this year’s annual Intel International Science and Engineering Fair. This event is the largest pre-college scientific research event in the world, and brings together seven million high school students from around the globe, who develop their own original scientific research projects and compete to win the prestigious award.
World’s Fastest Mobile Phone Charger
The Lynbrook High School senior’s invention does not look complicated at first glance – this tiny charging device is just a black, rectangular type of super capacitor that is around an inch long. However, do not be fooled by the size. This super capacitor is able to hold a significant amount of energy compressed within a small space. It then uses this energy to charge a gadget in just a few seconds and can last up to 10,000 charge-recharge cycles—ten times the number of cycles an ordinary rechargeable battery could support.
Khare demonstrated the ability of her supercharger invention to power an LED device. In her description of her project, as seen on the California State Science Fair outline, she said that her goal when she made this project was “to design and synthesize a super capacitor with increased energy density while maintaining power density and long cycle battery life”. She added, “Electrochemical super capacitors have attracted attention as energy-storage devices because they bridge the gap between current alternatives of conventional capacitors and batteries, providing higher energy density than standard capacitors and better power density than batteries. Despite these benefits, super capacitor energy density is much lower than batteries and increasing energy density remains a key challenge in super capacitor research. She also mentioned her inspiration behind the project “the rapid growth of portable electronics” and the necessity to develop “efficient energy-storage technology to match the development”.
In an interview with NBC news, Khare said that she picked this particular design challenge because she was fed up with her mobile phone battery always dying. This made her focus on super-capacitors and nano-chemistry where she worked at the nano-scale “to make significant advances in many different fields”. She also designed her device versatile enough so it can be used in roll-up displays or any fabric-based materials.
In Intel’s news release, they mentioned that Khare won the prestigious award because she recognized that energy-efficient storage devices are a crucial part of our society. This supercharger device also has the potential to work on car batteries, not just portable gadgets.
Aside from the Intel Young Scientist Award, Khare also won $50,000 for her amazing invention and is heading off to college at none other than Harvard University. No wonder then that tech giant Google, has also shown an interest in talents of Miss Khare.
When this technology will be available for mass consumption is unknown; however, until then all we can do is keep charging our mobile phones with regular chargers or use replacement batteries from companies such as A1 Battery Pro.
