In-Production Recycling of Active Materials from Lithium-Ion Battery Scraps

Having a closer look at the details, recycling of scraps from the production of lithium-ion batteries is different from recycling of spent batteries. On the one hand it is less dangerous on the other hand pristine electrodes retain the original non-aged quality and thus the separation process is more difficult. Two different separation mechanisms, one mechanical and one based on the solvent N-methyl-2-pyrrolidone, are examined in this work. The resulting separated coatings are directly re-applied on new electrodes and electrochemically characterized in full cells.
