Technically the whole sum of the battery is recyclable. However it must be dissassembled and dismantled, a complicated process, which is why Almost NONE are. Despite their proliferation, Since EV's aren't exactly widely adopted.
The growth of ICE cars around the world is going to outstrip EV manufacturing capability for years to come. For ever, once subsidies become too high for taxpayers to accept, EV sales will crash. EV cars measure just 0.167% of global auto fleet, One out of every 600 cars, Auto industry Spent BIllions on outfitting factories to make cars that only saturate 1% of all new auto sales. Just to make them Environmentalists whine it takes 30,000 lbs (15 tons) of raw material to make a 3000 lb car. It takes Over 4000+ tons of rock/ore to make One electric car, ICE engines made with iron/aluminum come from scrap by melting down cans and scrap metal. EV's require fresh resources of cobalt, lithium, copper, etc. You have to start an industrial revolution over again but instead of coal/iron; you're now digging up HALF the periodic table all of which is dug, mined, processed, manufactured, and shipped using fossil fuels. Under the guise of technology which is supposedly gonna "Rid us" of fossil fuels. Driving is only a small portion of a cars energy embodiment/life cycle, there's heavy energy investment in the beginning and late stages of it's life, namely manufacturing and recycling.
It takes 1000x more lithium to make an EV battery than a laptop battery.
