"From scooters to motorcycles, sportscars, school buses, trucks, trains, and even planes, it seems we are entering the era of electrified mobility. This has been due in large part to the rapidly falling costs and improving performance of lithium-ion batteries. Better batteries are enabling an increasingly wide array of electric personal, light, and heavy-duty vehicle technologies. The growth in deployments of lithium batteries will inevitably create a large flow of retired or used batteries. By 2030, analysts predict that retirements could exceed half a million vehicles annually or over 2 million metric tonnes of batteries per year."
