Stanford University scientists have invented the first high-performance aluminum battery that’s fast-charging, long-lasting and inexpensive. Researchers say the new technology offers a safe alternative to many commercial batteries in wide use today.
We have developed a rechargeable aluminum 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,
said Hongjie Dai, a professor of chemistry at Stanford. Our new battery won’t catch fire, even if you drill through it.
Dai and his colleagues describe their novel aluminum-ion battery in An ultrafast rechargeable aluminum-ion battery
, which will be published in the April 6 advance online edition of the journal Nature.
Aluminum has long been an attractive material for batteries, mainly because of its low cost, low flammability and high-charge storage capacity. For decades, researchers have tried unsuccessfully to develop a commercially viable aluminum-ion battery. A key challenge has been finding materials capable of producing sufficient voltage after repeated cycles of charging and discharging — via redwolf.newsvine.com
