Thread: New Device Batteries Last Longer, Charge Faster

U.S. scientists said they have invented a cheap, long-lasting and flexible battery made of aluminum for use in smartphones that can be charged in as little as one minute.

The researchers, who detailed their discovery in the journal Nature, said the new aluminum-ion battery has the potential to replace lithium-ion batteries, used in millions of laptops and mobile phones.

Besides recharging much faster, the new aluminum battery is safer than existing lithium-ion batteries, which occasionally burst into flames, they added.

Researchers have long tried but failed to develop a battery made of aluminum, a lightweight and relatively inexpensive metal that has high charging capacity.

Cool.
Now fit solar panels to the phuking things and we're good to go.

Stanford Uni. Cal. holds the patient. Nice work boys.

Made me wonder when these might be available, but that seems to be a ways off.

But more improvements will be needed to match the voltage of lithium-ion batteries, Dai added.

"Our battery produces about half the voltage of a typical lithium battery," he said. "But improving the cathode material could eventually increase the voltage and energy density. 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. I see this as a new battery in its early days. It's quite exciting."
