A Multifunctional Mesoporous Janus Separator With Optimized Mass Transport Regulation Enabling 800‐Cycle Lithium‐Oxygen Batteries
ABSTRACT Lithium‐oxygen batteries (LOBs) deliver ultrahigh theoretical specific energy but suffer from limited cycle life caused by lithium dendrite growth, anode corrosion, and cathode passivation. Developing interfacially compatible functional separators is an effective solution, yet coordinating fast ion conduction...
