Most existing regeneration strategies rely on compositional compensation while neglecting electronic-level regulation, and lack research on spontaneously formed, electrochemically unfavorable interfaces (rigid interface) that impede ion transport. Herein, we demonstrate a ligand-mediated electronic modulation strategy using a lithium-aluminum acetylacetonate complex (LAAE), where acetylacetonate (acac) functions as an electronic mediator rather than a conventional chelator. Through \u03c0\u2192d orbital coupling with high-valence cobalt sites, acac redistributes Co\u2013O bonding characteristics, creating an electronically compliant surface. This adsorption-induced bond weakening preferentially destabilizes defect-associated Co\u2013O linkages, facilitating the removal of electronically inactive cobalt species and oxygen vacancy passivation, while lowering interfacial ion transport barriers. Simultaneously, lithium replenishment from Liacac-derived species together with Al3+ incorporation contributes to stabilizing the layered framework. The regenerated LCO (R-LCO-Al) achieves a near-ideal stoichiometry with suppressed oxygen vacancies and restored structural ordering, delivering a high specific capacity of 179.9 mAh g\u22121 at 0.5 C (3.0\u20134.5 V) and 87.0% capacity retention after 200 cycles, rivaling commercial LCO. These findings establish electronic-structure modulation as an effective strategy for closed-loop regeneration of degraded oxide cathodes.<\/jats:p>","DOI":"10.1093\/nsr\/nwag369","type":"journal-article","created":{"date-parts":[[2026,6,14]],"date-time":"2026-06-14T16:06:39Z","timestamp":1781453199000},"source":"Crossref","is-referenced-by-count":2,"title":["Electronic
