Pyrite and quantum dots in your next battery?

Earlier this month we saw researchers seeing success by mixing air into lithium ion based batteries and today we hear of a different experiment aimed at increasing battery life.  As was discussed in the previous article the inevitable formation of crystals inside the battery is what prevents a battery from fully recharging and eventually being unable to hold any charge whatsoever.  Researchers have experimented with adding millions of iron pyrite quantum dots of varying sizes to lithium and sodium ion batteries and found they can make cells which charge more quickly than standard cells and survive more recharging cycles.  There is still a lot of work to be done, if you are interested in reading up on the research you can follow the links from Slashdot.

"The problem is that when the size of the crystals drop below a certain size they begin to react chemically with the electrolytes which prevents them from recharging. Now, however, a team of engineers from Vanderbilt University report in an article published in the journal ACS Nano that they can overcome this problem by making the nanocrystals out of iron pyrite, commonly known as fool's gold."

If device manufacturers wanted to give consumers devices that don't degrade as fast over time, they would just make the batteries easily swappable.
Still, this might make its way into some industrial applications.

It does not matter if say the Laptop device's battery improves by hundreds of percentage points over the previous generation's batteries, or is swappable. The laptop/other device OEMs have a software/firmware method for planned obsolescence, the laptop OEMs will just customize their graphics drivers, and never offer any graphics driver updates, among other methods. For Any device, that hardware could last for years, but the Laptop/other OEMs are much worse than even the VW folks, in making sure their software/firmware cheats the end users out of some extended useability, or other features. The Ugly Cloud is taking over computing with its paid for services model and Ad driven OS business model! So even your swappable batteries will be drained by the Ads!

Pyrite is alright with me.

thank god. this post brings the pcper conversation back to levels i'm comfortable with... confound you sir, and your thought provoking proclivities!
