Share A shredded electric vehicle battery can yield recyclable metals, but it is often cheaper for batterymakers to use new materials. Argonne National Laboratory Millions of electric cars are coming. What happens to all the dead batteries? May. 20, 2021 , 12:44 PM The battery pack of a Tesla Model S is a feat of intricate engineering. Thousands of cylindrical cells with components sourced from around the world transform lithium and electrons into enough energy to propel the car hundreds of kilometers, again and again, without tailpipe emissions. But when the battery comes to the end of its life, its green benefits fade. If it ends up in a landfill, its cells can release problematic toxins, including heavy metals. And recycling the battery can be a hazardous business, warns materials scientist Dana Thompson of the University of Leicester. Cut too deep into a Tesla cell, or in the wrong place, and it can short-circuit, combust, and release toxic fumes.
