Description:

Complete Recycling is a basic prerequisite for closing material usage loop of Li-ion batteries and is thus of increasing importance for the economic efficiency and sustainability of such energy storage systems. Since lithium in particular is largely lost in conventional recycling processes, it should be recovered from the so-called black mass right at the beginning of the process chain. Otherwise  a dissipation of Li via various material streams of the overall process can not be avoided. In the research project \"EarLiMet\", therefore, a comprehensively resource-efficient, predominantly hydrometallurgical recycling of the valuable components in Li-ion batteries up to the TRL 5/6 level is to be developed. The concept pursued in EarLiMet aims at a zero-waste approach, which requires a complete consideration and balancing of the entire process.
