摘      要：Aluminum-air batteries(AABs)are considered the most promising candidates in advanced clean energy conversion and storage due to their low density,high specific energy,and abundant aluminum resources;however,the development of AABs is constrained by inevitable parasitic side reactions and anodic surface passivation film *** present work introduced an innovative hybrid corrosion inhibitor consisting of potassium stannate,decyl glucoside,and 1,10-decanedithiol to regulate solid-liquid interface reactions in alkaline *** findings indicated that the optimal hybrid corrosion inhibitor could reduce the hydrogen evolution rate from 0.2095 to 0.0406 mL cm^(-2)min^(-1),achieving an inhibition efficiency of 80.62%.The surface analysis discussed in detail the evolution process of the solid-liquid interface after the introduction of the hybrid corrosion inhibitor into the *** and theoretical calculations revealed that decyl glucoside enhanced the adsorption and coverage efficiency of the hybrid corrosion inhibitor through the“micelle solubilizationeffect and optimized the structure and properties of the solid-liquid *** study also contributed valuable insights into the corrosion inhibition mechanism at the solid-liquid interface of alkaline AABs.
