Fully charging your mobile phone battery in just 20 seconds may be a reality soon rather than later following the invention of a super-capacitor by an American teenage girl university student.

Eesha Khare, 18, won $50,000 from the Intel Foundation for inventing the device that will fit inside mobile phone batteries, charging the phone in just 20 to 30 seconds.



Khare, a Californian university science student, was awarded the Young Scientist Award by the Intel Foundation for inventing the device which can last up to 10,000 charge-recharge cycles.



This compares with rechargable batteries which can only be recharged about 1,000 times.





Accepting her prize at the Intel Foundation Awards, Khare told US television network, NBC, that she was inspired to create a practical solution after growing frustrated that her mobile phone battery kept dying.
