Sometimes, but not often. These are mostly 1st gen EV batteries, so they're pretty old. It's mentioned in the article that once capacity diminishes to the point of effecting range the old battery is replaced. Old units can be refurbished. These units could also be situations where the car surrounding the battery failed (accident, hail damage, etc) and they decided to scrap it and reclaim the battery.
