Recycling Graphite for Vanadium Redox Flow Batteries: Options for Usage and Critical Integredients

Abstract

Already in 2010, a working group of the European Commission, analysed arround 41 materials and came to the conclusion about their criticality and the risk of supply safety and their ecomic importance. As a result, around 14 matrials were judged critically, and this included graphite as well [8]. For some industry areas, Graphite is estimated as a critical material [9]. For this reason, the importance of Recycling Graphite is growing and it is necessary to look for recycling material.
