Water purification could be the key to more electric cars

Engadget -------- Humanity is going to need a lot of lithium batteries if electric cars are going to take over, and that's a problem when there's only so much lithium available from conventional mines. There may be an oddball solution for that, however: turn the world's oceans into eco-friendly mines. Scientists have outlined a desalination technique that would use metal-organic frameworks (sponge-like structures with very high surface areas) with sub-nanometer pores to catch lithium ions while purifying ocean water. The approach mimics the tendency of cell membranes to selectively dehydrate and carry ions, leaving the lithium behind while producing water you can drink.
