Atmospheric Corrosion-Driven Redox Coordination Enables Spontaneous Carbonate Conversion of Lithium-Ion Battery Cathodes

acts both as a proton carrier and as a coordinating ligand, sustaining the redox-coordination loop. This chemistry-driven approach redefines corrosion as a tool for selective redox transformations and offers a reagent-free, scalable pathway for LIB recycling under ambient conditions.
