The big issue with the recycling is the cost to actually do the separations. EV battery packs are not just Li, Co, and Ni, there is so much plastic, some exotic, some over molded, intertwined with the batteries and inside the pack, add to that some toxic electrolytes, and it ends up that mining new raw materials is cheaper and easier than trying to recycle. I am amazed that the recycling industry has no caught up, but keep in mind from 2008 until just a few years ago, the numbers of EVs on the road was still quite small, and most of those were relatively new, so not a lot of salvage material in the pipeline.
The bigger issue is the battery changes over time effectively obsoleting cars that are less than 10 yrs old if they do need a battery pack. EVs are essentially disposable vehicles now.
