Tesla
expects to sell 500,000 cars world-wide by 2018, and its 2020 production would be one million vehicles, thanks in part to its coming Model 3 car. With a price tag of $35,000, it would be about half the cost of the Tesla Model S sedan. The company says it already has received nearly 400,000 orders for the Model 3.
Those orders will require a lot of lithium.

“In order to produce half a million cars a year…we would basically need to absorb the entire world’s lithium-ion production,” Tesla Chief Executive Elon Musk said at the unveiling of the Tesla 3 model on March 31.


And this is just from one (of many) company ramping up electric car manufacturing.
