Yes. It's essential to remove the lithium, nickel and other rare-earth elements from them. However, even if they're not dismantled, they can also be used for renewable energy storage and deliver a slower release of energy to power domestic or commercial properties.
New EV battery recycling businesses are starting to emerge. The elements are sold back to the EV car industry to manufacture new batteries over again. Manufacturers like Renault have built-in recycling and repurposing of batteries into their 'closed loop'.
It's also worth pointing out that EV batteries are assembled from many smaller cells. So, unlike your single mobile or laptop battery, each cell is frequently and thermally managed by the car's computer. This means EV batteries can easily last 10 or 15 years.
