Electric car maker Tesla Motors (s TSLA) hasn’t just blazed its own trail when it comes to designing and building a hot electric car.

This week Tesla revealed more details about its plans to build a massive — the largest of its kind in the world — battery factory in the U.S. that will produce enough lithium-ion batteries by 2020 to outfit 500,000 electric cars.
