Battery Materials Made Using Crab Shells
MTorrice writes "Crab shells usually are just a nuisance that you have to crack and dig through to get the delicious meat inside. But one team of materials scientists thinks the shells could help them fabricate materials for long lasting batteries. The team used the nanostructures (abstract) found in the crustacean shells as templates to make sulfur and silicon electrode materials for lithium-ion batteries. Sulfur or silicon electrodes have a 10-times greater theoretical energy storage capacity than electrodes used in commercial batteries."
From the title it sounds like they're using the crab shells as electrodes, when really they just used the nano-structures in the shells to fabricate better electrodes.
Now if we only had a radio made of coconuts.
usually are just a nuisance that you have to crack and dig through to get the delicious acid inside.
It's probably better than endeavoring to construct a mnemonic memory circuit using stone knives and bearskins.
Crab shells kill mold, mildew and fungus too...
Some weird product we found to treat a wet area... all natural and all that bs.. gave it a shot. was called clear shell...
Dammed if it didnt work.. I guess i've never seen a moldy crab, even tho they're wet all the time. lol
So far it's worked better than all the other anti crap we've tried there.
Still bizarre... liquid crabshells to kill mold.
Just that. Unkosher batteries.
So if I understand this correctly, by increasing the surface area of the electrodes, you increase storage density. We already knew that. The problem is those electrodes corrode over time... ions swap between the two plates, which is why we don't go through the effort of manufacturing them with lots of little pits and twists in them, because they'll just corrode that much faster. No pure metal can resist this, and alloys that can generally make poor foundations to build batteries on. Plus there's manufacturing cost. For something like a car battery... that's important. For something like a cell phone, I can see some merit in making batteries with a higher energy density at the tradeoff of shorter life. Of course, they're already pretty short right now...and expensive. :(

Either you can do it, or you can't. My laptop runs on electricity, not theory.
There's for example this guy who appears to be very well-versed in making supercaps using glass jars and chemicals in white bottles obtained from unusual sources. He has a few videos where he uses chitin from fungi to make them.
He's not the only guy doing this, but for every video on this level of science there is a dozen perpetual motion devices. If you know of more interesting amsci, please link.

So, how long till the adn of crabs is put into some microbes to industrially make those materials? 25+ years?
Any chance Zebra mussels would do as well? We got lots of them\.
Taste like crab talk like batteries
finally. my lifelong dream of a multi-core cellphone with the pungent aroma of dried crab is so close i can almost taste it.
Good people go to bed earlier.
My girlfriend got a job demonstrating these down at the beach.
They were using the 'C Cell' size battery and comparing theirs to major brand batteries.
Part of her job was to pull the covers off of the batteries so people wouldn't know which brand they were using.
So....
When people ask me what she does foo a living I say:
She shells C-Cells by the sea shore.

I know you caught me.
I made up the part about having a girlfriend.
No brain, no pain.
The "delicious" is misplaced. I guess the rest of the article is of the same accuracy level.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
