This study reports an innovative Al-air battery system utilizing new organic non-aqueous electrolytes. The Al surface activating electrolytes involved tetra-butylammonium fluoride tri-hydrate (TBAF∙3H₂O) salt dissolved in different “traditional” non-aqueous battery solvents, such as propylene carbonate (PC), tetra-ethylene glycol dimethyl ether (TEG-DME), acetonitrile (ACN) and dimethyl sulfoxide (DMSO). Conductivity and activation energy evaluations of the different electrolytes are reported alongside electrochemical measurements and surface characterization, using high-resolution scanning electron microscopy (HR-SEM). This study concludes that the most successful activation of the aluminum surface is obtained with the use of an electrolyte consisting of 1 M of TBAF tri-hydrate salt in PC, resulting in high anodic currents. The active species present in the electrolyte were detected and analyzed with the use of an Attenuated Total Reflection Fourier Transform Infra-Red (ATR-FTIR) spectroscopy method. The X-ray photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy (EIS) measurements are indicative of the formation of an active, and yet protective fluoride containing layer, once the Al surface is exposed to the electrolyte media. Half-cell and primary Al-air cells evaluation with the use of different discharge anodic currents were performed utilizing various TBAF tri-hydrate salt concentrations dissolved in the organic solvent. The promising results achieved in this study constitute a foundation for future electrolyte solutions developed for Al-air battery systems.

这项研究报告了一种利用新型有机非水电解质的创新型铝空气电池系统。Al表面活化电解质包括四丁基氟化铵三水合物（TBAF∙3H ₂O）溶解在不同的“传统”非水电池溶剂中的盐，例如碳酸亚丙酯（PC），四甘醇二甲醚（TEG-DME），乙腈（ACN）和二甲基亚砜（DMSO）。使用高分辨率扫描电子显微镜（HR-SEM），报告了不同电解质的电导率和活化能评估，以及电化学测量和表面表征。这项研究得出的结论是，通过在PC中使用由1 M TBAF三水合物盐组成的电解质可获得最成功的铝表面活化，从而产生高阳极电流。使用衰减全反射傅立叶变换红外（ATR-FTIR）光谱法对电解质中存在的活性物质进行检测和分析。一旦Al表面暴露于电解质介质中，X射线光电子能谱（XPS）和电化学阻抗能谱（EIS）的测量就表明形成了活性的但仍具有保护性的含氟层。利用溶解在有机溶剂中的各种TBAF三水合物盐浓度，对使用不同放电阳极电流的半电池和一次铝空气电池进行了评估。这项研究中取得的有希望的结果为未来为铝制空气电池系统开发的电解质解决方案奠定了基础。利用溶解在有机溶剂中的各种TBAF三水合物盐浓度，对使用不同放电阳极电流的半电池和一次铝空气电池进行了评估。这项研究中取得的有希望的结果为未来为铝制空气电池系统开发的电解质解决方案奠定了基础。利用溶解在有机溶剂中的各种TBAF三水合物盐浓度，对使用不同放电阳极电流的半电池和一次铝空气电池进行了评估。这项研究中取得的有希望的结果为未来为铝制空气电池系统开发的电解质解决方案奠定了基础。
