posted an interesting article that I will post here in it's entirety. Food for thought:

THE DOWN SIDE TO LITHIUM BATTERIES

http://www.blogsmithmedia.com/www.autoblog.com/media/2008/08/john-media-photo-3-opta.jpg (http://www.autolinedetroit.tv/)

Uh-oh. In the pell-mell race to develop lithium-ion batteries for plug-ins, EV's and hybrids, has any automaker taken a hard look at where all that lithium is going to come from? Guess what? Not only are global lithium supplies pretty tight, prices are about to skyrocket.

Today, the United States imports almost all of its lithium. We get most of it from Chile, then Argentina, and a little bit from Canada and Zimbabwe. The only producer in America is actually a German company, Metallgesellschaft, which has a mine in Nevada. Yet, even though we import most of our lithium, the United States is the world's largest processor of the material.

John McElroy (http://www.autolinedetroit.tv/whatisad/) is host of the TV program "Autoline Detroit" (http://www.autolinedetroit.tv/). Every week he brings his unique insights as an auto industry insider to Autoblog readers.

But a lot of others want to get in on the game. China, no surprise, is emerging as a major player. It's buying all the lithium it can from Australia. China does have some lithium sources of its own, but they're mainly in Tibet. (Say! Do you think that's another reason why they're so hard-core about keeping Tibet within the People's Republic?)

Right now, all lithium producers around the world are running flat out, and plans are afoot to ramp up production dramatically. But while there's a lot of lithium in planet Earth, I'm told that it's kind of like oil shale: it's there, but it's not cheap or easy to get.

And there are other competing demands for using lithium, like in producing ceramic, glass and aluminum. And for air conditioning systems. It's even used by the pharmaceutical industry for treating depression. Now the auto industry wants to start using huge amounts of it.

"Demand will soon outstrip supply. We're going to see prices spike," Christian M. Lastoskie, Ph.D., of the Department of Civil & Environmental Engineering, at the University of Michigan, tells me.

You'd think that such a valuable material would get recycled a lot, but that's not the case. Today, only 3% to 4% is recycled, and while that will probably increase, it won't increase a lot. Recycling lithium takes a lot of energy, so much so that recycled lithium costs five to six times more than getting it from virgin material.

That could prompt battery researchers to search out other alternatives for advanced batteries, but so far not much has happened. "Everyone searching for alternatives keeps coming back to lithium because it offers so many advantages in weight and storage capacity," says Lastoskie.

It sure looks like the auto industry is locking itself into a future that depends on a precious resource, which is in tight supply, and that has to be imported. I'm just asking folks, but in our rush to get better fuel economy are we about to replace one form of dependency for another?

Ever heard the word "recycling"? Google it up.

Ya know, you might want to think about copyright laws before you paste such articles into this forum. Fair use allows a few short paragraphs, but not much more.

The news is nice to see, and I'm glad you are posting it, but I suggest you trim things a bit, or Derwin could get into some big legal trouble.

As long as you cite the original article and author, there usually is no problem. The other thing is if they have the statement that this material cannot be used or reprinted with out their consent - then ther might be a problem. My wife is a writer, editor and proofreader.

Joe is absolutely right. AZ has also provided a link to their site to trace the origins!!! Usually this is sufficient unless otherwise stated!!!

I'm not going to do the research right now because it's late and I took some Benadryl, but the "peak lithium" debate had some traction a while back. Most researchers say that it's a crock.

There's plenty of lithium that hasn't been mined (harvested?) yet in developing nations and even in the US of A. Plus a lithium-ion battery has very little lithium in it, and the amount is being reduced with better battery chemistry. Other researchers say that there is more than enough to go around even if the entire US transportation fleet was converted to electric overnight.

The problem is obtaining the lithium, which will drive the price up. But, again, the lithium is just one element of the cost of the battery. Cheaper anodes, cathodes, manufacturing, shipping and what-have-you can drive the total cost down.

Additionally, recycling plays into the equation. Most people don't recycle li-ion batteries today - shame on us. But 1,000 lbs battery packs needed for vehicles will have to be recycled - by law undoubtedly.

And lets not forget that lithium is just one battery chemistry. Others are being advanced, as well as non-battery solutions like super-capacitors and fuel cells. And all that is just for electric drive vehicles, Sterling and Brayton cycle engines that use gas or domestically produced bio-fuels more efficiently are also being developed and will certainly find a place in the transportation segment.

So I'm not getting all worked up about it.
