Addressing Inherent Challenges to Chemical Relithiation of Cycled End‐of‐Life Cathode Materials
Advanced Energy Materials, EarlyView.The evolution of fluorine surface species is tracked during a low‐temperature redox mediator relithiation process for direct recycling of cycled NMC 622. A washing step is presented as a solution for mediating adverse effects of surface contamination. Redox mediator relithiation is shown to be a rapid, efficient method that can be applied to cycled NMC

Critical Metals Hydrometallurgy [PDF]
JOM, 2015 In 2013, the E.U. Ad hoc Working Group on Raw Materials published its second criticality analysis report. The motivation to write this report came from the observation that in today’s world, our economies become more and more dependent on a number of metals and raw materials. Achzet et al.
