Redistributing Cobalt and Tungsten From WC–Co Soft Scrap Toward Sustainable Cathode and Coating Materials for Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
A sustainable upcycling strategy transforms tungsten carbide–cobalt (WC–Co) soft scrap into high‐performance cathode materials. Recycled Co with trace nickel (Ni) is resynthesized into stabilized LiCoO2 with superior high‐voltage durability, while the recovered tungsten is further utilized as tungsten trioxide to enhance Ni‐rich cathode interfaces ...

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 ...
