A new battery could store ten times as much energy as lithium ions



Batteries not included

The batteries are great. They supply many of the brands of the future, from smartphones to electric cars. The problem is, of course, that batteries never seem to last long enough with one charge – and their environmental impact is significant.

Now, however, an all-star team of researchers from Caltech, NASA's Jet Propulsion Laboratory and NASA Honda says they have developed a fluoride-based battery that delivers up to ten times the energy density of a traditional lithium-ion cell can and less resources needed for manufacturing.

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 ̵

"Fluoride ion batteries offer promising new battery chemistry with up to ten times the energy density of current lithium batteries," said Christopher Brooks. a researcher from the Honda Research Institute and a co-author of the newspaper in a press release. "Unlike Li-ion batteries, FIBs pose no safety risk due to overheating. Obtaining raw materials for FIBs has a significantly lower environmental impact than the lithium and cobalt extraction process."
