A battery that could charge your phone in one minute? Ask Stanford.


Scientists at Stanford University say they have developed an ultrafast aluminum battery that can be charged in as little as one minute.

Researchers say the long-lasting and inexpensive prototype could also become a safer alternative to other batteries in wide use today, such as environmentally unfriendly alkaline batteries or lithium-ion batteries, which are flammable.

“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,” said Stanford chemistry professor Hongjie Dai, in a press release. “Our new battery won’t catch fire, even if you drill through it.”

The prototype is also bendable, meaning pliable electronic devices could become a possibility.

The technology for making the commercially viable aluminum battery, something that has eluded scientists for decades, was discovered when scientists paired graphite with aluminum.

This resolved a key durability issue, allowing the Stanford battery to last 7,500 charging cycles without weakening.

Past aluminum batteries developed in other laboratories died after only 100 charging cycles, and lithium-ion batteries, which are used in the majority of electronic devices, typically last only 1,000 cycles.
