Recent advances and interfacial challenges in solid?state electrolytes for rechargeable Li?air batteries

Among the promising batteries for electric vehicles, rechargeable Li-air (O2) (LABs) have risen keen interest due to their high energy density. However, safety issues of conventional nonaqueous electrolytes remain bottleneck practical implementation LABs. Solid-state (SSEs) with non-flammable and eco-friendly properties are expected alleviate concerns, which become a research focus in field Herein, we present systematic review on progress SSEs LABs, mainly focusing interfacial existing between electrodes. The discussion highlights challenges feasible strategies designing suitable
