Cell Phones Could Be Charged In A Minute?
A cheap and long-lasting rechargeable battery, that charges fast could be in stores soon .It’s made of aluminum, which makes it safer than to the conventional lithium ion and alkaline batteries that is in use now. The challenge is trying to find a voltage after repeated cycles of charging and discharging. An international led by Stanford’s Hongjie Dai discovered a simple solution using graphite. An aluminum anode, graphite cathode, and ionic liquid electrolyte were put in a flexible pouch coated with a polymer.
The team hope these will replace the batteries we use today. It will also charge your phone within one minute instead of hours. It’s much better for the environment as well. “Lithium batteries can go off in an unpredictable manner in the air, the car or in your pocket,” Dai says in a news release. “Our new battery won’t catch fire, even if you drill through it.”
