Authors: Prof. Dr. Bernd Friedrich; M.Sc Lillian Peters Abstract<\/strong><\/p>\n\n\n\n Due to the rising demand of Lithium-Ion Batteries in\nmany applications like electric mobility or portable consumer goods the scrap\nvolumes arising in the future are likely to increase, too. Nonetheless, exact\ncalculations are challenging because the highly dynamic market, also in view of\nbattery chemistries, is subject to uncertainties. Scenario-based approaches by\nmeans of several parameters such as the cell weight, the battery lifetime, the\ncollection rate or the export quota lead to helpful estimations, which are\ncrucial for recyclers. In terms of the process technology there are many\nconcepts and process paths available serving to recover relevant metals and\nmaterials and such contribute to the global target of a circular economy\nof raw materials. Depending on specific interests, the prerequisites in terms\nof knowledge or existing equipment technology, different paths can be chosen. Still,\nin many processes less noble but valuable components, such as the core element\nLi, are presently not recovered. <\/p>\n\n\n\n For each process path alternative a \u201crecycling efficiency\u201d (RE) can be consequently calculated. The European Union has defined a threshold for an efficient recycling process, namely a 50 wt.% RE referring to cell level. In contrast to that, only a few companies in Europe are capable of realizing this aim by mobilizing sufficient products from this waste instead of dumping important metals such as Lithium in a slag. This presentation aims to give an insight into the prevalent concepts for holistic recycling with a special focus on Li, and highlights their shortcomings and benefits. Hereby potentials and needs for political or technological modifications from the status-quo are pointed out. <\/p>\n","protected":false},"excerpt":{"rendered":"
