How do you dispose of an electric car battery

First reused and repurposed, then recycled In order to make use of the remaining capacity, the batteries can be broken down to salvage smaller components for reuse and refurbishment, or they can be repurposed and used in a less demanding application, such as stationary storage.

They get to a point where their capacity/performance deteriorates below any useful case. If the battery cannot be used for alternative storage purposes, the valuable materials are separated out, such as cobalt, lithium salts, stainless steel, copper, aluminum, and plastic.
