New battery could charge your phone in just 60 seconds

chargeDesigners of a new aluminum-ion battery say it could charge a smartphone in about a minute and endure far more rechargings than today’s lithium-ion batteries. Only problem is it has about half the voltage, Stanford University reports via the Telegraph.

“Otherwise, our battery has everything else you’d dream that a battery should have: inexpensive electrodes, good safety, high-speed charging, flexibility, and long cycle life,” says Stanford professor Hongjie Dai.

Compared to alkaline batteries, he says, the Stanford invention is better for the environment, and unlike lithium-ions, it won’t catch fire—”even if you drill through it,” he says.

Researchers have been trying to make a viable aluminum-ion battery for decades, Phys.org reports. The problem has been getting materials that create enough voltage after multiple rechargings.  More
