The ecoLiga project balances the sustainability in terms of manufacturing and recyclability of different carbon materials. One of the goals is to recommend suitable materials and battery designs to increase sustainability. Accordingly, a central issue of the project is the possibility of mobilizing battery components to close material cycles and create carbon materials based on a design for recycling. In this way, the fields of battery production and recycling can be linked in terms of content, and cooperation paths can be identified to move in the field of sustainable innovation development. In particular, the developed methods are validated using lithium-sulfur batteries as an example of an innovative battery system. In this context, innovative pre-treatment methods such as flotation are used to ensure enrichment of graphite and carbon materials and holistic maximization of yield with the target of resynthesis.
