3 Million EV Auto Batteries, Where will they Go?

Seems we have about 3 million EV auto batteries coming up to be retired from their 10 year run. Where will they go? What will happen to them, in the ground, laying around like old tires, where? 

According to Bloomberg, seems countries around the world are holding the auto companies responsible for dealing with the batteries and making sure they do not get put into landfills. According to the story, it seems all auto companies are recapturing money by selling these perfectly good batteries for use as storage system from home to commercial applications around the world. Only then after they truly wear out in 20-30 years will the rare earth elements be recaptured to be used over again in new products.

Seems that from Tesla, GM, Toyota to BYD that the auto batteries have become a total side business that is expected to yearly run around $550 Billion a year in building and selling a Box of Energy or Powervault or whatever they end up calling it.

In fact you could very well end up buying your next EV auto along with a home power storage system from your local dealership.
