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 ...

Bifunctional Role of Surface Cobalt Doping as a Lithium‐Residue Scavenger and Surface Stabilizer in Single‐Crystalline Ultrahigh‐Ni Cathodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Surface cobalt coating on single‐crystalline NCA acts as a lithium‐residue scavenger and structural stabilizer. The protective layer suppresses moisture‐ and CO2‐induced reactions, mitigates crack formation, and inhibits the formation of NiO‐like rock‐salt phases. This dual‐function surface engineering enhances interfacial stability and electrochemical

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...
