Comments on: Can Lithium Batteries Compete with Lead? http://www.cosjwt.com/blog/?p=111 Just trying to highlight what's right and wrong in the world of EE and other things.

One must also analyze how much energy it takes to affordably access the Lithium reserves in the world. Thank you for the clarification and for taking the time to post.

Using the figures presented by leading producers of 0.6 kilos of carbonate per KWH of battery capacity, each million tonnes of Li is sufficient to power 530 million vehicles requiring a 10 KWH battery. At current carbonate prices, the lithium cost per battery is about 1% of the total battery cost. The Salar de Uyuni contains about one sixth of the world's resources.
