Addressing Inherent Challenges to Chemical Relithiation of Cycled End‐of‐Life Cathode Materials

open access: yesAdvanced 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
