In this work, the aluminum-air battery performance is improved by adding nonionic surfactant (nonoxynol-9) to battery electrolyte (4.0 M NaOH). The efficiency of nonoxynol-9 is determined using hydrogen gas evolution and electrochemical measurements. The surface analysis is explored using scan electron microscope and energy dispersive X-ray spectroscopy. Battery performance is investigated at 20 mA cm⁻². The results show that the battery performance is significantly improved by adding nonoxynol-9. This is due to the low corrosion rate of aluminum in 4.0 NaOH solution resulted from physical adsorption of nonoxynol-9 on aluminum surface. The surfactant suppresses the hydrogen gas evolution and increases the anode utilization and capacity density. The maximum inhibition efficiencies of nonoxynol-9 from hydrogen gas evolution and electrochemical measurements are 85.6% and 92.8%, respectively at 2.0 mM. Nonoxynol-9 behaves as a cathodic-type inhibitor and its adsorption complies with Freundlich type isotherm. The adsorption of surfactant on the aluminum surface is emphasized by surface analysis.

在这项工作中，通过向电池电解质（4.0 M NaOH）中添加非离子表面活性剂（nonoxynol-9）来改善铝空气电池的性能。使用氢气放出和电化学测量来确定Nonoxynol-9的效率。使用扫描电子显微镜和能量色散X射线光谱仪探索表面分析。在20 mA cm ^{-2的条件下}研究电池性能。结果表明，通过添加壬诺酚9可以显着提高电池性能。这是由于壬醇9在铝表面上的物理吸附所致，铝在4.0 NaOH溶液中的腐蚀速率较低。表面活性剂抑制氢气逸出并增加阳极利用率和容量密度。从氢气放出和电化学测量得出的壬诺酚9的最大抑制效率在2.0 mM时分别为85.6％和92.8％。Nonoxynol-9表现为阴极型抑制剂，其吸附符合Freundlich型等温线。表面分析强调了表面活性剂在铝表面的吸附。
