Adsorptive Exhaust Gas Cleaning for Recycling of Li-Ion-Batteries

Abstract: Increasing the usage of lithium-ion batteries requires sufficient recycling strategies to save resources. In the collaborative research project LithoRecII a recycling process was investigated to completely recover solid and liquid value components of spent Li-ion batteries. The process combines discharging, dismantling, shredding, extraction, drying and mechanical separation steps. The grinding and drying stages are flushed with an inert drying gas producing an off-gas loaded with different organic solvent com… Show more

“…11 This being said, there have been many small-scale advances, developing physical, pyrometallurgical and hydrometallurgical techniques that focus on extracting all parts of the battery. [11][12][13][14] However, a large bias towards the cathode remains, with the anode, comprised primarily of graphite, either being sold as scrap, pyrolyzed, or used as a reducing agent in pyrometallurgical recycling processes. 12,[15][16][17] Current commercial EVs, LIBs can contain around 11 times more graphite than lithium by mass.…”
