Harnessing 4f Electron Itinerancy for Integrated Dual‐Band Redox Systems Boosts Lithium‐Oxygen Batteries Electrocatalysis

/CoO-based LOB exhibits an ultra-low charge-discharge polarization (0.46 V) and stable cyclic performance (1088 hours). This work breaks through the traditional limitations in catalyst activity and stability, providing new strategies and theoretical insights for developing high-performance LOBs powered by rare-earth elements.
