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.
The new aluminum battery is also safer than existing lithium-ion batteries, which occasionally burst into flames, they added.
A team lead by chemistry professor Hongjie Dai at Stanford University in California made a breakthrough by accidentally discovering that graphite made a good partner to aluminum, Stanford said in a statement.
A prototype aluminum battery recharged in one minute, the scientists said.
