Li-ion battery pretreatment process assessment. D6.3
report
Lithium ion batteries contain many critical raw materials (e.g. Ni, Mn, Co, and Li) and end-of-life batteries
are available and collected in the Netherlands. However, an infrastructure to recycle these is not here yet in place. Due to geopolitical tensions regarding the supply of critical raw materials and EU’s battery regulations, the development of a battery recycling infrastructure in the EU is needed with a specific role for the Netherlands. Battery recycling often involves a pretreatment process, followed by chemical processing to recover the (critical) metals. The pretreatment process involves multiple steps, among which are shredding and sieving, and results in the formation of a fine powder fraction, called black mass, which is enriched in these critical metals and graphite. In the Netherlands, an innovative pretreatment process is in development at pilot scale. This process is suitable for processing charged batteries by shredding them under inert atmosphere circumventing the need of a discharging step and simultaneously being able to usefully apply the released energy.
