Just over a year ago, and spurred by an article in Time, I wrote a post on the possible global supply of lithium, which is used in renewable batteries, and a major choice for use in the batteries of electric vehicles, such as the Chevy Volt. Since the story has acquired more recent interest this week, and with new information, it is worth re-visiting the topic.
I began the original post by noting that our first introduction to these batteries was in our role as an Explosives Lab when we found out - in a series of experiments a long time ago - that they can blow up if handled wrongly. And it turns out that such a risk is still around, though not that common. But to put the event in context:
Fifteen incidents in the last two decades were serious enough to warrant a decision to re-route a plane or perform an emergency landing, according to FAA data. For instance, in 2008, there were nine battery accidents resulting in two minor injuries. To put that figure in perspective, that year 3.3 billion lithium batteries were transported on 77 million flights, including 56 million passenger and combination passenger/cargo flights.
Based on that data, one's chances of being on the same flight with someone who suffers a minor injury because of a malfunctioning battery was about 1 in 28 million in 2008. In comparison, the one-year odds of dying from a car accident in the U.S. are 1 in 6,584, according to the National Safety Council.
Since we also look at processing, I became curious about where and how the lithium is mined. Recently, however, h/t to JoulesBurn, there was an article by Jack Lifton explaining some additional production issues. So what I thought I’d do is to integrate some of this additional information into a more up-to-date post.
It turns out that most lithium comes from salt lake deposits such as those in Chile and Bolivia.
The biggest deposit in the world lies in the Salar de Uyini, Bolivia, which is also the world’s largest salt flat. A quick look through Google Earth gives the location, with the white in the picture being the salt flat, and not snow. La Paz, the capital of Bolivia is at the top. Full article at: Electric Vehicles
IF there is a future for electric vehicles, that future lies with super capacitors and not batteries.
I wonder if the slow discharge capacitor is possible, especially for long periods of time

That’s a pretty serious charge. I see you’re up on your current events.

What about the Bonneville Salt Flats then?

Death of the Electric Car: Li-ion Batteries Too Valuable for Plug-In Vehicles
We need an Illudium Q-36 Explosive Space Modulator.
It works great for fork lifts in enclosed warehouses, some people even like the smell.
Saw their exhibit at the Washington DC Auto Show. They may have the answer.
What about the Bonneville Salt Flats then?
The Bonneville Salt Flats is administered by the Bureau of Land Management for public use and enjoyment. Due to its unique geology, history, and scenic beauty, the Bonneville Salt Flats was designated an Area of Critical Environmental Concern in 1985

If they are looking to use the same lithium battery that my camera uses, they may want to improve its cold temperature operation.
There was a thread on FR recently where everyone was blowing off as old news an article about capacitor paper. I wonder if *that* was the big deal about the capacitor paper?
Its more than that - it is positively electrifying!
???????
They always react negatively. But there definitely is a current on this thread that has generated interest in the subject.
reading your posts, I may blow a fuse..... :)
