Here is a nice cheerful analysis of why the potential exists for shortages of cheap lithium:
The Trouble With Lithium
Some highlights include:
$this->bbcode_second_pass_quote('', '[')list]South America holds nearly 80% of the known Global Lithium Reserve Base.
Only Lithium from the Brine Lakes and Salt Pans will ever be useable to manufacture batteries.
The deposits in Nevada are in decline and many older Lithium deposits in the USA are now uneconomic.
Exclusive dependency on Lithium Ion batteries, where the Lithium will overwhelmingly come from South America, would be like being dependent on South America for 100% of our oil supply.
Future Lithium Carbonate Demand could exceed 2% of the Global Li2CO3 Reserve Base per annum.
The expansion of lithium mining required to support a plug-in hybrid world would be enormous relative to present day production
Towards the end of this report you see another type of battery technology offered as a solution to the impending "lithium shortage", so there is obviously some possible bias going on here.
There was an
analysis of this report on The Oil Drum, and the following rough conclusions were made:
$this->bbcode_second_pass_quote('', '*') With the existing known reserve base of 13.4 million tonnes of lithium and less than 10 mbd of oil, we could run 4 billion cars in 2050.
* If we assume most residents of the planet are living in dense cities in the third world with degrees of public transportation comparable to dense western cities today, then 3-5 billion cars should be enough to satisfy people's aspiration for automobile transport by that time.
