The concept of Graphene Super Capacitor might be the history changer for tomorrow’s world of fast charging. A battery, high energy storage charges slowly and discharges slowly this ability is energy density. Similarly, capacitor , a low energy storage charges rapidly and discharges rapidly which is the power density. Combining the best of both will lead to fast charging and slow discharging. Super capacitors lies between the concept of this two energy storage methods.
Eesha Khare, a graduate from Lynbrook High School California developed a super capacitor prototype that charges very rapidly and would last longer for more charging cycles. And was runner up at Intel International Science and engineering Fair (2013) bringing out this prototype. Its still prototype in the current state but proved to be work.
Her prototype could be fully charged within time interval of 20-30 seconds and hold the charge for longer like on other similar devices. It lasts for 10,000 cycles compared to batteries in current world 1000 cycles. Much greater achievement in field of energy storage.
Nano scale and mass scale fabrication hasn’t been practically possible on today’s world. Gradually, scaling up this prototype will lead to powering phones and electric cars. Like increasing the technology the maH of batteries will also certainly increase in the future.
Imagine plugging your phone in, charging it for about 20 second and of that charge it will work one day or more.
