As electric vehicle production revs up across the globe, an inherent consequence will be the mutually growing number of retired lithium-ion batteries that, unlike traditional lead-acid car batteries, are difficult to dispose of.A new Cornell University-led study identifies several keys to sustainably managing the influx, with an emphasis on battery chemistry, second-life applications and recycling
