Recycling or reusing lithium batteries?

Recycling technologies are varied . Of all the recycling technologies, pyrometallurgical processing, or smelting, is the most mature and can recover key metallic elements. Mechanical processing can recover valuable cathode materials directly, and hydrometallurgical processing can be lower cost. Tesla backs recycling. Automakers are choosing a wide array of applications for reuse of batteries. BMW and Nissan are commercializing residential storage products, while Daimler has started operating a large 13 MWh system. Tesla, on the other hand, pursues recycling as its NCA cathodes are not suitable for most stationary storage needs. Reuse options are limited. Second-life batteries offer only limited cost savings, especially as new cell prices continue to fall. Still, with more efficient testing, sorting, and repackaging, second-life systems could be made more competitive for ap...
