NASA Invented The Negative Battery That Could Keep Phones Charged For A Week


It seems that we could enjoy phones that we would only have to charge once a week in the future.

There’s a new type of battery that you only need to charge once a week that has just been developed by NASA. The research has been published in the journal Science.

A power cell that lasts eight times longer

This amazing power cell has been made using fluoride instead of lithium, and this allows it to last eight times longer.

The Sun reported that it could be used in order to power the next gen of smartphones or even future NASA spacecraft on their way to deep space.

“Researchers at Caltech, Nasa’s JPL center, Lawrence Berkeley National Lab and the Honda Research Institute developed the fluoride-based batteries,” the Sun announces.

It seems that this technology has been discussed for decades, but the new cell marks the first time when researchers have developed a rechargeable version.

The reason is that the chemical properties of fluoride have typically made it challenging to work with.

Flouride batteries have a higher energy density 

“Fluoride batteries can have a higher energy density, which means that they may last longer – up to eight times longer than batteries in use today,” said Caltech researcher Robert Grubbs.

“But fluoride can be challenging to work with, in particular, because it’s so corrosive and reactive.”

Fluoride’s high density makes it more difficult to stabilize at room temperature; it runs hot at 150 degreed Celsius or more.

In order to get around this, researchers have added a brand new type of electrolyte liquid.

This could stabilize the batter and produce the world’s first rechargeable fluoride cell.

According to the team, this new design shows that fluoride is a viable battery and you could help make for batteries that would last much longer.

“We are still in the early stages of development, but this is the first rechargeable fluoride battery that works at room temperature,” study author  Simon Jones.

“We’re unlocking a new way of making longer-lasting batteries. Fluoride is making a comeback.”
