Dissolution of Spent Lithium‐Ion Battery Cathode Materials: Overlooked Significance of Aluminum Impurities

open access: yesAdvanced Science, EarlyView.
During the mechanical crushing of retired lithium‐ion batteries, aluminum foil from current collectors may penetrate NCM active crystals through frictional contact, forming more stable Al─O bonds. The dissolution behavior of critical metals in NCM cathodes will be influenced to varying extents by different mechanisms in various hydrometallurgical ...

New Insights into Heavy Metal Sequestration Through Metal‐Phenolic Network‐Confined Nano‐HFO: Overlooking Iron Utilization and Modulating Electron Density

open access: yesAdvanced Science, EarlyView.
Iron‐based nanocomposites are widely used for trace heavy metal removal, but the low utilization of HFO nanoparticles remains a challenge. Here, a metal‐phenolic network (MPN) strategy is proposed to confine nano‐HFO within polystyrene beads, creating a negative electrostatic field and optimizing electron density at oxygen sites. This approach enhances

Gram‐Scale Preparation of Tri‐Coordinated Single‐Atom Catalysts for CO2 Electrolysis in Large‐Scale Membrane Electrode Assembly

open access: yesAdvanced Science, EarlyView.
A low‐cost and tri‐coordinated SAC (g‐NiN3) is prepared in gram‐scale using metal ionic liquid [Bmim]2[NiCl4] as precursors. The g‐NiN3 achieves an excellent overall performance for eCO2‐to‐CO in a large‐scale MEA reactor. The overall performance in g‐NiN3 is superior to that of commercial Ag nanopowders, and manifests as one of the state‐of‐the‐art ...
