Abstract
Lithium-ion batteries (LiBs) play a key role in the electrification of our society, and contain materials that are associated with supply risks, rendering them critical- or strategic raw materials (CRMs and SRMs, respectively). Examples of such materials are Li, Co, and Mn (CRMs), or Ni and Cu (SRMs). Recycling is a key contributor to relieve some of the pressure on the supply of these materials. This dissertation focuses on mixed battery waste streams of complex and varying chemistries, and on how this end-of-life product influences hydrometallurgical recycling, with the ultimate goal of designing a flexible, closed loop recycling process that combines
high product quality with minimal environmental footprint....
