“…Therefore, it poses a high risk to the Li anode regarding structure collapse over prolonged cycles. [140][141][142] Structure modification and rational composition design can eliminate the corrosion of Li anodes, thus stabilizing the anodic interfaces. Table 2 summarizes some recent advances based on anode alternatives to improve the performance of Li-air batteries.…”

Alkali metal–air batteries (AMABs) promise ultrahigh gravimetric energy densities, while the inherent poor cycle stability hinders their practical application. To address this challenge, most previous efforts were devoted to advancing the air cathodes with high electrocatalytic activity. Recent studies have underlined the solid–liquid–gas triple‐phase interface around the anode can play far more significant roles than previously acknowledged by the scientific community. Besides the bottlenecks of uncontrollable dendrite growth and gas evolution in conventional alkali metal batteries, the corrosive atmospheric gases, intermediate oxygen species, and redox mediators in AMABs cause more severe anode corrosion and structural collapse, posing greater challenges to the stabilization of the anode triple‐phase interface. This work aims to provide a timely perspective on the anode interface engineering for durable AMABs. Taking the Li–air battery as a typical example, we have a critical review of the latest developed anode stabilization strategies, including formulating novel electrolytes to build protective interphases and alleviate corrosive attacks, fabricating advanced anodes to improve their anti‐corrosion capability, and designing functional separator to shield the corrosive species. Finally, we highlight the remaining scientific and technical issues from the prospects of anode interface engineering, particularly materials system engineering, for the practical use of AMABs.
