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

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
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 ...
