The project "greenBattNutzung" is part of the BMBF's cross-sectional initiative Battery Life Cycle and accompanies the two associated competence clusters "Recycling & Grüne Batterie (greenBatt)" and "Batterynutzungskonzepte (BattNutzung)" in order to manage and ensure the achievement of the respective cluster goals. Within the framework of this accompanying project, the AIP is responsible for the development of scenarios regarding the future flows of spent batteries as well as the conception and execution of economic assessments of second-use concepts and recycling processes to support the decision-making of industry and politics.

Initial Situation and Problem Definition
With the increasing market penetration of lithium-ion batteries, the requirement to reduce negative environmental impacts as far as possible is growing. To achieve this, the lifetime of the battery cells must be maximized and the material cycles of the raw materials must be closed. To this end, two new research clusters have been initiated by the BMBF as part of the cross-sectional initiative "Batterielebenszyklus". The "Batterienutzungskonzepte" cluster focuses on extending battery lifetime and supporting the development of new material and cell concepts. The "Recycling & Grüne Batterie" competence cluster lays the foundations for the sustainable recycling of batteries and raw materials as well as the closing of material and substance cycles in the battery life cycle. The size and structure of these two competence clusters require support from an accompanying project so that the achievement of the cluster goals can be managed and ensured.
Objective and Approach
Against this background, the accompanying project takes over the central coordination and management of the two competence clusters as well as the bundling and integration of the research results from the cluster projects. This strengthens the networking of the different research institutions and ensures an optimal transfer of results in the cluster network, which supports the achievement of the cluster goals. In addition, the accompanying project will carry out an overall evaluation of various end-of-use/end-of-life options for batteries in terms of their economic, technological and ecological impact.
