Current price is $500 to $700 / kwh - though Nissan supposedly has even lower price for their Nissan Leaf. Let us take $500 / kwh. Since 24kwh battery is said to use 4 kg of Li - 1 kwh would use some 170 gm. Taking metalic Li price as $40 / kg, we are looking at some $7 / kwh. Let us make that $10/kwh.
So, currently only 2% of the battery cost is because of Lithium. How much would that have to increase to make the battery cost 5 times ? (Lithium price needs to go from $40/kg to $2,040/kg or 126 times)
We can cross check this using information from here. "They showed that you need 1.4 kg of lithium carbonate per kilowatt hour of battery." That gives a cost of $11 / kwh (using $8/kg).

But it's quite dilute actually in seawater (0.1-0.2 ppm). Like you say, cheaper and easier to get the salts that were in seawater.AndyH wrote:There's PLENTY available in sea water. It's cheaper and easier to get the salts from areas formerly under water. There are recently discovered lithium deposits in the US as well.
