The battery that can charge your mobile in just ONE minute
Researchers at Stanford University, California, say their new aluminium battery could end up with a safe and more convenient energy source than the lithium models used in most mobiles and laptops.
Stanford chemistry professor, Hongjie Dai, said the new device was a breakthrough.
Writing in Nature journal, he said: "We have developed a rechargeable aluminium battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames.
"Our new battery won't catch fire, even if you drill through it.
"Millions of consumers use 1.5-volt AA and AAA batteries. Our rechargeable aluminium battery generates about two volts of electricity.
"That's higher than anyone has achieved with aluminium."
The prototype battery was able to fully charge more than 7,500 times without losing any capacity.
