Engineering Residual Rock‐Salt Reconstruction through Near‐Surface Fluorine Regulation for Stable 4.6 V Cycling of Regenerated Spent Layered Oxide Cathodes

ABSTRACT Direct regeneration enables high‐value recovery of spent layered oxide cathodes, but their high‐voltage reuse requires stabilization of both regenerated surface and lattice oxygen beyond bulk compositional restoration. Here, we report a high‐voltage upcycling strategy fo...
