Decoating of Electrode Foils from EOL Lithium-Ion Batteries by Electrohydraulic Fragmentation
Decoating of Electrode Foils from EOL Lithium-Ion Batteries by Electrohydraulic Fragmentation
Lyon, T.; Mütze, T.; Peuker, U. A.
In order to ensure environmentally friendly mobility, electric drives are increasingly being used. As a result, the number of used lithium-ion batteries has been rising steadily for years. To ensure a closed recycling loop, these batteries must be recycled in an energy- and raw materialefficient manner. For this purpose, hydrometallurgical processes are combined with mechanical pretreatment, including disintegration by mills, crushers and/or shears. Alternatively, lectrohydraulic fragmentation (EHF) is also of great interest, as it is considered to have a selective fragmentation effect. For a better comparison, different application scenarios of EHF with other methods of mechanical process engineering for the treatment of lithium-ion batteries are investigated in the present study.
