针对碱性铝/空气电池，提出了丁烷四醇和二硫苏糖醇两种原始多元醇化合物作为电解液添加剂。结果表明，它们能有效地延缓铝阳极的自腐蚀，提高铝阳极的性能。二硫苏糖醇增加放电容量的能力强于丁四醇。这种改善主要是由于抑制了析氢副反应。用傅里叶变换红外光谱（FT-IR）证实了二硫苏糖醇和铝离子形成的六元环配合物的形成。利用扫描电子显微镜（SEM）和x射线光电子能谱（XPS）对铝阳极的表面形貌和成分进行了表征。结果表明，二硫苏糖醇可以通过动态共价键在铝阳极表面形成均匀稳定的保护层。
For alkaline aluminium/air battery, two original polyol compounds of butantetraol and dithiothreitol are proposed to act as electrolyte additives. It shows that they can retard the self-corrosion of aluminium anode, and enhance its performance effectively. Dithiothreitol has a stronger ability to increase the discharge capacity than butantetraol. The improvement is mainly attributed to the suppression of the side reaction of hydrogen evolution. The formation of the six-membered ring complexes formed by dithiothreitol and aluminium ions is certified by the Fourier transform infrared spectroscopy (FT-IR). The surface morphology and composition of the aluminium anode are characterised by the scanning electron microscope (SEM) and the X-ray photoelectron spectroscopy (XPS) analysis. It shows that dithiothreitol can form a uniform and stable protective layer through dynamic covalent bonds on aluminium anode surface.
