Teen Innovator Eesha Khare and the Supercapacitor That Sparked Global Curiosity
At just 18 years old, Eesha Khare, a student from the United States, stepped into the global spotlight after developing a groundbreaking concept in energy storage — a supercapacitor capable of charging far faster and lasting far longer than conventional batteries.

Her innovation earned her the Intel Foundation Young Scientist Award at the 2013 Intel International Science and Engineering Fair (ISEF), one of the world’s most prestigious competitions for young scientists. The recognition placed Khare among the brightest student innovators of her generation.
The idea was born from a familiar frustration: slow-charging batteries and devices that lose power too quickly. Rather than improving traditional lithium-ion batteries, Khare explored supercapacitors, an alternative energy-storage technology known for rapid charging and exceptional durability.
Using advanced materials, including graphene-related components, Khare designed a small supercapacitor prototype that demonstrated remarkable performance in laboratory conditions. During testing, the device charged fully in 20 to 30 seconds and could be reused thousands of times without noticeable degradation — a sharp contrast to standard batteries that gradually lose efficiency.
However, Khare was careful to present her work accurately. The prototype was not installed in smartphones or used to instantly charge real consumer devices. Instead, it powered small electronic systems, such as LEDs and lab-scale setups. The idea of ultra-fast phone charging was discussed as a future possibility, not a commercial reality.
What made her work stand out was its potential impact. If supercapacitor technology can be scaled effectively, it could one day transform charging speeds for smartphones, electric vehicles, and renewable energy systems. Researchers worldwide continue to build on this field, exploring how such technologies might shape the future of energy storage.
Eesha Khare’s achievement did not promise overnight revolution — but it offered something equally valuable: a credible scientific step forward. Her work demonstrated how curiosity, discipline, and honest research can open new paths in science.
More than a decade later, her story remains a powerful reminder that innovation often begins with asking better questions — and that young minds can help shape tomorrow’s technologies through thoughtful, realistic progress.
