In Li-O2 batteries, Li2O2 serves as the primary cathodic material but its wide band gap imparts insulating properties. Regulating composition and morphology of enables construction a novel structure with exceptional electrochemical performance. Herein, we introduce an organic salt containing cobalt ions, acetylacetonate (Co(acac)2), into electrolyte. We exploit cation migration characteristics under electric field to facilitate generation decomposition Co-doped Li2O2, achieving gradient control optimized growth Li2O2. Moreover, Co(acac)2 molecule stabilizes properties LiOx species mitigates side reaction. situ UV-vis XANES spectra reveal direct interactions between O2-/LiO2, highlighting superior reversibility enhanced batteries. Both experimental theoretical results indicate that this battery system exhibits rapid reaction kinetics, reduced overpotential 520 mV extended cyclability, surpassing 400 cycles lower polarization.
