Tesla electric cars are, to this day, distinguished by reliability at high mileage.

One such success of Elon Musk is the creation of a battery with a lifetime mileage of over ... one million miles! Or 395 times around the globe at the equator! A stunning result! If you average 130-140 miles a day, then such a battery will last for 20 years of operation. That is, it is almost comparable to the resource of an internal combustion engine.

How did Musk's team achieve such a phenomenal result?
