Peak Lithium? Why Should You Care?

What the heck is lithium and why should you care? First things first; what is lithium?
My first encounter with lithium was as a surreptitious high school participant in a science experiment. My teen buddies and I got a small piece of lithium and dropped it into a toilet to let it fizz.

That was exciting. But beyond the plop-fizz thing, what else should you know about lithium?

Here is an excerpt from Wikipedia:
“According to theory, lithium was one of the very few elements synthesized in the Big Bang, although its quantity has vastly decreased since that time. The reasons for its disappearance, and the processes by which new lithium is created, continue to be active matters of study in astronomy. Though very light, lithium is nevertheless less common in the universe than any of the first 20 elements.”
To learn more, go to Wikipedia.

All this is mildly interesting, but it doesn’t answer the question “why should I care?”

Here’s why.

President Obama’s and others’ hoped for transformation of our transportation systems –including your car—from petroleum based to electric, depends on rechargeable batteries. The best chemical bet at this time seems to be lithium batteries. Lithium ion batteries are the majority choice, although lithium phosphate batteries are less apt to catch on fire – but they too depend on stable and abundant supplies of lithium.

The common thread is easy to see: Lithium. Note this phrase in the above Wikipedia quote: …less common in the universe than any of the first 20 elements. And that leads to the next point.

Where in the world do you find lithium? Not at Home Depot. Here is a quote from Peak Oil Review from its February 9 2009 newsletter (ask me how to receive this if you’re interested).
In the rush to build the next generation of hybrid or electric cars, a sobering fact confronts both automakers and governments seeking to lower their reliance on foreign oil: almost half of the world’s lithium, the mineral needed to power the vehicles, is found in Bolivia — a country that may not be willing to allow much access to the mineral. (Peak Oil Review, 09 Feb 2009).
Recently Simon Romero wrote about this in the NY Times. Here is a quote:

“We know that Bolivia can become the Saudi Arabia of lithium,” said Francisco Quisbert, 64, the leader of Frutcas, a group of salt gatherers and quinoa farmers on the edge of Salar de Uyuni, the world’s largest salt flat. “We are poor, but we are not stupid peasants. The lithium may be Bolivia’s, but it is also our property.”

How much lithium is in Bolivia and elsewhere? The article goes on to say that “The United States Geological Survey says 5.4 million tons of lithium could potentially be extracted in Bolivia, compared with 3 million in Chile, 1.1 million in China and just 410,000 in the United States. And beyond the current use of lithium in cell phones and laptops, what will be the impact of plug-in hybrid automobiles on the supply of lithium? Here’s what Mitsubishi spokesman said on the BBC News, November 9, 2008: “Mitsubishi, which plans to release its own electric car soon, estimates that the demand for lithium will outstrip supply in less than 10 years unless new sources are found.”

Now technology optimists will always say, and sometimes be right in saying, that we can always find alternatives. Still, the time is short for alternatives; GM is pinning its hopes for survival on the Volt, to be available in 2010. Not sure
Google “peak lithium” and you’ll find this WSJ blog. http://blogs.wsj.com/environmentalcapital/2009/02/03/peak-lithium-will-supply-fears-drive-alternative-batteries/
This blog describes alternatives such as zinc-air batteries. However, one very large obstacle: they aren’t rechargable and have a short lifespan. That’s akin to saying “except for that Mrs. Lincoln, how did you like the play?”

So are plug-in hybrid automobiles truly a climate-friendly, peak-oil mitigating alternative to the internal combustion engine?
