US scientists said they have invented a cheap, long-lasting and flexible battery made of aluminium 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 aluminium-ion battery has the potential to replace lithium-ion batteries, used in millions of laptops and mobile phones.
Besides recharging much faster, the new aluminium 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 aluminium, a lightweight and relatively inexpensive metal that has high charging capacity.
