英文摘要	Aluminum electrodes undergo severe hydrogenation and self-corrosion in alkaline solutions. Here, a novel inorganic-organic hybrid corrosion inhibitor, constituted by Na2SnO3 and ethylene glycol, was formulated. Electrochemical tests demonstrated that the inhibitor could effectively suppress the self-corrosion at the anode, increasing the anode utilization from similar to 16 % to similar to 43 % and the specific energy density from similar to 543 to 1577 Wh kg(-1). Moreover, a relatively stable discharge effect was observed. Based on surface morphology analysis, a mechanism for the deposition of Na2SnO3 and ethylene glycol on the surface of the aluminum electrode was proposed. It was suggested that the presence of ethylene glycol is conducive to a more uniform and denser deposition of tin on the surface of the aluminum electrode, a condition that can inhibit corrosion more efficiently as well as improve the discharge effect. The analysis of the entire adsorption energy using the Vienna ab initio simulation package supported this hypothesis.
