Stage‐Specific Roles of Deep Eutectic Solvents in Recycling of Spent Lithium‐Ion Batteries

Advanced Energy Materials, Volume 16, Issue 13, 1 April 2026.
Deep eutectic solvents (DESs) offer tunable acidity, redox, and coordination properties for selective recycling of spent lithium‐ion battery cathodes. Through co‐dissolution, single‐ and two‐metal separations, DESs enable sustainable recovery of critical metals for closed‐loop regeneration of battery‐grade materials, advancing a circular economy for ...

A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Metal Sorption Characteristics of a Macromolecular Resin Containing D2EHPA.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1994
In previous works, we studied the divalent metal sorption characteristics of di-(2-ethylhexyl) phosphoric acid (D2EHPA)-ImSorb in batch and column operation modes. The study was made to elucidate whether the sorption behavior varies with the two different methods for preparation of extractant containing resins or not, using both Levextrel resin and ...
