The following is from an article written on Clean Technica The most important component of vehicle batteries is lithium. Lithium is already in high demand as it used in rechargeable batteries for laptops, mobile phones, and digital cameras. In 2015 the estimated demand for Lithium is 138,500-265,000 tons and in 2020 the demand may reach 175,000 to 500,000 tons, with most of the demand going towards batteries.
Currently the majority of the world’s supply of lithium comes from Bolivia, Argentina and Chile. While recycling batteries to extract lithium makes perfect sense, financially it is not worth it since the cost to recycle the lithium exceeds the cost of mining new lithium.
So we know there is a market for most of the electric car battery components once the battery is no longer usable. We know there is recycling infastructure in place ( not plentiful but at least in place) but still the fine details need to be worked out before we all jump up and say EV leaves a tiny footprint.
