New Lithium-Air Battery Delivers 10 Times the Energy Density 281
Al writes "A company called PolyPlus has developed lithium metal-air batteries that have 10 times the energy density of regular lithium-ion batteries. The anode is made up entirely of lithium metal, and the surrounding air acts as the cathode, making the batteries incredibly energy dense. Previous efforts to make lithium metal batteries have been stymied by the sensitivity of lithium to water in the air. The new batteries use a sophisticated membrane to protect the lithium anode and PolyPlus has even created a version that works underwater, by drawing oxygen through the membrane. Lithium metal-air batteries could be light-weight power sources for demand for plug-in hybrid vehicles and consumer electronics; IBM also recently announced that it would develop lithium metal-air batteries for the energy grid and for transportation."

Anything that breaks the membrane and allows moisture to come into contact with the anode will start a nice fire. Or you can microwave them. Or blend them.
First they came for boxcutters, but I wasn't a terr'rist, so I didn't say anything.
Then they came for hammers, but I wasn't a terr'rist, so I didn't say anything.
Then they came for screwdrivers, but I wasn't a terr'rist, so I didn't say anything.
Then they came for microwaves, but I wasn't a terr'rist, so I didn't say anything.
Then they came for blenders, but I wasn't a terr'rist, so I didn't say anything.
Then they came for can-openers, but I wasn't a terr'rist, so I didn't say anything.
So here I sit starving, unable to open this frigging can of food, and even if I could, I'd have to eat it cold because I can't nuke it and without tools I can't fix the furnace. Now if only I could find a rock and a lithium battery, I'd be able to cook it!

My former girlfriend was a very sensitive person.
It never occurred to me before, but now that you mention it, I think this is exactly what she meant by the term.

Dominating in "Guitar Hero" does not make you a musician. Just like knowing the Star Wars prequels sucked doesn't make you a filmmaker. Or, having the AOL screen name "SugarBabeeGrl710" doesn't make you girl.

Wait, I'll just go get my metal compressor and my neutron cannon out of the basement, and call the lithium hydride delivery service. Hmm, should I also order a pizza and a blow-job?

Don't use these Batteries in Space!!!! (Score:4, Funny)
I needed some batteries for the life support systems on my spacesuit, so i went and bought some of these new fangled Lithium-Air Batteries and they don't work worth a crap. They worked fine in the airlock but as soon as I stepped out on my space walk I was gasping for air as my life support system inexplicably shutdown.

These Batteries are Horrible, just Horrible!!!! I have to trust my life to batteries for supplying me with Oxygen and keeping my temperature constant.

Two space gloved thumbs down!
