(Some Guy)   Worried about rare earth minerals driving up the cost of your electronics? Don't worry, California boffins are building battery anodes out of the not-so-rare earth you know as "sand"   (ucrtoday.ucr.edu) divider line 25

"Rare Earth" materials aren't that rare. There is even a mine down in Missouri. But, as with many things, China is manipulating the price to drive competition out.

On an industrial scale, finely ground California beach sand does not seem like a good starting point. The essence of the new process is the step where finely ground SiO2+Mg+salt yields foamed silicon when heated.

Also, current batteries don't use rare earths.  Lithium isn't a rare earth.  NiMH used one (Lanthanum or an REE alloy called "Mischmetal").  But those are 10 years obsolete.  Also, in this case, the Silicon is replacing graphite (Carbon).  Also not a rare earth.

Still, Lithium-Silicon batteries will be great once they work out the main bug (cycle life).

I see revolutionary changes to lithium batteries that never make it to market about once a quarter.

I hate the word "boffin."

"And when there were no rare-earth minerals to be found, we used sand."

There are no boffins in California.  Only British scientists are boffins, the rest are scientists.

That's true, but Lithium Silicon will make it to market.

Many Boffins died to give us this information.

"Boffin".....

boffin....

Bof, yeah that's got to end.

I'm guessing subby is a hipster trying to make "boffins" happen here in the US.

Subby: Just stop it. Now.

In America, a boffin is a boston cream-muffin hybrid, like a cronut.
 
2014-07-12 01:01:36 PM
Cronuts are why the Neanderthals went extinct, and why Nonna has a spectacular treasure trail.

are they somehow taking advantage of sillicate-based sands semi-quartz status to procure a piezo-electric response to being 'dunked' through an electric field created by dissociate ions pouring from human-keratin-based cathodes in a grylls-flavored sterile electrolyte bath?
 
2014-07-12 01:37:11 PM
Well I had the quartz recognition part, I guess I'm going way too far into the renewable band.

That's so fetch.

F*ck you, and your boffin, subby.
 
2014-07-12 09:23:36 PM
Yes, because I need to know how to make energy when there's nothing left but sand.

Armageddon for dummies.

This does work out the cycle life issue. The article states that these anodes last three times longer than current carbon anodes.

Bolgers, Bracegirdles, and Brandybucks call for further research.

It always reminds me of "puffin", so I imagine things being invented by seabirds with colorful beaks.

1000 cycles in the lab is a big step towards solving the cycle life issue, but that doesn't mean it is completely solved.  They still have to get it to scale to production levels.

Lithium Silicon batteries are getting close, but they aren't there yet.  If they were, battery factories everywhere would be setting up production lines.
