It's interesting to note that the lead acid batteries in ICE cars are among the most (possibly the most) fully recycled products. A large percentage of them make their way back to recyclers at end-of-life and when they do, they are fairly highly recyclable. New lead acid batteries are made of up to 80% recycled material.
Glass and aluminium are also extremely recyclable, but a huge amount of post-consumer glass and aluminium still ends up in landfill. Whereas the logistics, economics and supply chain of lead acid batteries makes them ideal for recycling. And I'd expect EV batteries to comfortably surpass this high bar given how difficult it would be for an EV battery to somehow make it into landfill.
