Neutral electrolyte, such as synthetic seawater (SW), is a promising candidate for aluminum-air (Al-air) battery due to the alleviated hydrogen evolution along with anode self-corrosion. However, aluminum surface passivation in SW poses serious challenge battery's power generation. Following molecular self-assembly theory, 5-carboxylate benzotriazole (CB) was incorporated into β-cyclodextrin (β-CD), which (CB@β-CD) utilized an interfacial activator SW. CB could be released from β-CD, and activated surface, facilitating discharge. The specific capacity energy density of Al-air were achieved 2607.4 mAh/gAl 2.37 kWh/kgAl, respectively, at optimal CB@β-CD concentration 120 mg/L. Density functional theory calculations revealed that overwhelming adsorption guest molecule on Al (111) plane over its binding inside host (β-CD) accounted release ensuing activation effect.
