The charging device has been dubbed a supercapacitor by Esha Khare of Saratoga, California, the reported.
Khare wins $50,000 for her invention at the Intel International Science and Engineering Fair, held in Phoenix.
Khare has only used her supercapacitor to power a light-emitting diode (LED), but said that one day her invention will power cell phones, cars and any gadget that need a rechargeable battery.
The supercapacitor is flexible and tiny, and is able to handle 10,000 recharge cycles, over normal batteries by a factor of 10.
Khare is a student of nanochemistry, and is now heading to Harvard. Google has been in contact with Khare to discover how she plans to change the makeup of cell phone battery life, the report said.
