It’s not a very meaningful problem now, scaling is. If you have a growth of 50% per year (Tesla) it mean that the 20 years recycling is 1.5*20 = 3325X less. I

It’s not a very meaningful problem now, scaling is. If you have a growth of 50% per year (Tesla) it mean that the 20 years recycling is 1.5*20 = 3325X less. I hear that most of the recycling is from scrap production, if you have a 1% defect rate you have 30X more recycling from new production than from 20 year old batteries.
