Selective Lithium Recovery via Stepwise Transition Metal Crystallization in a Natural Deep Eutectic Solvent

Advanced Science, EarlyView.
A biodegradable, natural deep eutectic solvent (DES) is designed for preferential lithium (Li) leaching from various cathodes under mild conditions (60 °C, 8 h). Compared to traditional acids and DESs, it achieves >96% Li leaching from black mass with minimal transition metal dissolution via a stepwise reduction, complexation, hydrolysis, and ...

Sustainable Recovery and Reuse of Hard Carbon From Scrap and End‐of‐Life Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
As sodium‐ion battery (SIB) technology advances, sustainable end‐of‐life recycling is crucial. This study presents a direct recycling method for hard carbon (HC) using low‐temperature binder negation at 300 °C under nitrogen. Retaining structural integrity, recycled HC achieves 86–89% capacity retention over 200 cycles.

Understanding Structural and Compositional Evolution during NMC Cathode Direct Recycling via Solid‐State NMR

Advanced Energy Materials, EarlyView.
Direct recycling end‐of‐life lithium‐ion batteries (LIB) to recover high‐value cathode materials such as LiNixMnyCozO2 (NMC) requires method development and detailed characterization. In this work, the unique capabilities of solid‐state NMR in characterizing changes in local ordering within NMC cathode materials during recycling and upcycling as well ...

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
