Fool's gold could mean faster-charging batteries

However, the team discovered that when using iron pyrite quantum dots, the battery stores energy in a fundamentally different way, and the same chemical reaction doesn't occur. The work was led by graduate student Anna Douglas.

In a conventional lithium ion battery, the lithium ions enter a storage material during charging and leave during discharge. When lithium ions enter the prototype battery they react with the iron pyrite molecules -- which are comprised of one iron atom and two sulfur atoms -- to form lithium sulphur, and the iron atom moves out. On discharge, the reverse happens and the iron pyrite is reformed.

 

I think we can all agree that shorter charging times are awesome. Maybe Linus' battery needs will be fulfilled soon.

Maybe Fool's Gold was valuable...  :blink:

haha I always liked to imagine every element is there for a reason! This is proof of that.

I wonder what this will mean for electric cars...

that's a lot more taking place, I can't see these types of batteries having as long a lifespan when exposed to constant reconstructing on the molecular level. Also heat could be a problem, I will admit though, I've not looked far enough into the chemical reactions to figure out if it is or not.

Very interesting non-the-less.

Fool's gold isn't an element, it's FeS₂.

Fools gold isn't an element.

Damn it! You beat me to it.
