Essentially, we don’t expect any electric vehicle batteries to get scrapped.
An entire industry exists to provide “second life” products from them by installing them in buildings to help manage the energy system better. If they cannot be re-used, then they will get recycled. Car companies are legally required to take batteries back and many say they really want to do this too – over 90% of the metals inside that battery can be reprocessed.
This would displace demand for newly mined materials in a decade’s time. Or to put it another way, the battery of tomorrow’s electric car will be made from the battery of the electric car of today.
