Both the Nissan Leaf and Chevy Volt are notably more expensive. This is, in part, because both cars have much larger battery packs, but it's also because those packs are made with more expensive Li-ion batteries. The 2012 plug-in Prius will use all Li-ion batteries, and Toyota says the plug-in version will be at least $3,000 more expensive than the standard Prius, no doubt in part because of the more expensive Li-ion batteries onboard. However, General Motors thinks the extra cost is worth it saying "...the fact that lithium-ion batteries have a higher energy-to-weight ratio and as a result weigh less than nickel metal hydride systems in similar applications means that they are cost competitive."

Have a look at the latest ore presentation and at the moment most demand is coming from small electronics(phones,laptops etc)which are growing fast.
Motor scooters and bikes are selling by the millions and are also converting to lithium.
So as the car sales increase how will we keep up.Open Mt Cattlin.
