California teen invents device that could charge a cell phone in 20 seconds

California teen invents device that could charge a cell phone in 20 seconds | cross pond high tech | Scoop.it

Eesha Khare is the mind behind a super-powerful and tiny gizmo that packs more energy into a small space, delivers a charge more quickly, and holds that charge longer than the typical battery. Khare showed off her so-called super-capacitor last week at the Intel International Science and Engineering Fair in Phoenix, Ariz. In her demonstration, she showed it powering a light-emitting diode, or LED light, but the itty-bitty device could fit inside cell phone batteries, delivering a full charge in 20-30 seconds. It takes several hours for the average cell phone to fully charge.

Khare also pointed out that the super-capacitor “can last for 10,000 charge cycles compared to batteries which are good for only 1,000 cycles.”

Philippe J DEWOST's insight:

Most of us have been dreaming of this at some point, right?

Graphene Supercapacitors: The End Of Batteries?

Graphene Supercapacitors: The End Of Batteries? | cross pond high tech | Scoop.it

Richard Kaner and his graduate student Maher El-Kady have been trumpeting graphene micro-supercapacitors that would combine the very fast charge and discharging capabilities of supercapacitors – hundreds of times faster than batteries – with the high energy density of batteries.

 

Now the researches say they have demonstrated a scalable fabrication process that could make their supercapacitors cheap to produce while expanding the possibilities for their use.

“We are now looking for industry partners to help us mass-produce our graphene micro-supercapacitors,” Kaner said in a statement.

Philippe J DEWOST's insight:

The process is almost as fascinating as the potential outcome ...
