Besides recharging much faster, the new 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.
A team led by chemistry professor Dai Hongjie at Stanford University in California made a breakthrough by accidentally discovering that graphite made a good partner to aluminum, Stanford said in a statement.
In a prototype, aluminum was used to make the negatively-charged anode while graphite provided material for the positively charged cathode. The prototype aluminium battery recharged in one minute.
“Lithium-ion batteries can be a fire hazard,” said Dai. “Our new battery won’t catch fire, even if you drill through it.”
