铝-空气电池的铝阳极在碱性电解液中易发生析氢自腐蚀，导致其放电效率较低，这是制约其产业化发展的关键问题。铝-空气电池电解质缓蚀剂的复配增效研究，具有重要的学术与实际意义。8-羟基喹啉（8-HQ）是环境中铝含量光谱测定的标准化合物，对铝合金有良好的缓蚀作用。本项目拟以8-羟基喹啉（8-HQ）为模型化合物，并与金属氧化物（ZnO、CaO）进行复配增效。将光谱分析技术引入碱性铝-空气电池电解质复合缓蚀剂的研究，将缓蚀组分之间的相互作用信息转换为物理光信号表达，考察分子8-羟基喹啉-金属离子（Al3+、Zn2+、Ca2+）复合物的分子荧光发射（波长、强度等）的变化特征，结合电化学测量和表面分析测量，考察复配增效的规律性，研究缓蚀各组分之间的相互作用，探讨协同机理，从而指导铝-空气电池电解液的研究，并为铝-空气电池的检测技术开发提供理论基础。

Al-air batteries have advantages of lower cost, high energy density and environmental friendliness. However, the main problem is the low columbic efficiency caused by its hydrogen evolution side-reaction. Developing the high-efficiency corrosion inhibitors is the core issue in the research of Al-air batteries alkaline electrolyte. 8-hydroxy quinolone (8-HQ) is important for the detection of Al3+ ions and has good corrosion prevention for Al alloy. This project intends to use 8-hydroxy quinolone as model molecule. The combination of 8-hydroxy quinolone and metal oxide (ZnO or CaO) is investigated to act as corrosion inhibitor for Al-air battery in 5M NaOH solution. The interaction between the inhibitive units will be studied by the variation of fluorescence excitation and attenuation. The scanning electron microscopy (SEM) and the microscopic Fourier transform infrared spectroscopy (Micro-FTIR) are used to examine the surface morphology and microstructure of Al alloy. The spectral analysis as well as electrochemical measurement will be adopted to elucidate the mechanism of the synergistic effect. It will help to seek the new principle for the selection of electrolyte additives of Al-air battery. The project can provide the theoretical support for the development of Al-air battery and provide novel idea for the detection of Al-air battery.
