new battery ten times power

Batteries Not Included

Batteries are great. They power many hallmarks of the future, from smartphones to electric cars. The problem, of course, is that batteries never seem to last quite long enough on a charge — and their environmental footprint is substantial.

Now, though, an all-star team of researchers from Caltech, NASA’s Jet Propulsion Laboratory, and Honda say they’ve developed a fluoride-based battery that could deliver up to ten times the energy density of a conventional lithium-ion cell — and that take fewer resources to manufacture.

The team describes the new battery in a paper published Friday in the journal Science. Basically, CNET reports, fluoride batteries have been around for a while — but they required oven-like temperatures of around 300 degrees Farenheit (150 Celsius) to function. The new battery, according to Caltech and company, can produce power at room temperature.

“Fluoride-ion batteries offer a promising new battery chemistry with up to ten times more energy density than currently available Lithium batteries,” said Christopher Brooks, a Honda Research Institute researcher and a co-author of the paper, in a press release. “Unlike Li-ion batteries, FIBs do not pose a safety risk due to overheating, and obtaining the source materials for FIBs creates considerably less environmental impact than the extraction process for lithium and cobalt.”
