铝空气电池用6061和7075铝合金阳极电化学性能

研究了工业6061铝合金（6061）、航空7075铝合金（7075）和纯铝作为铝空气电池阳极材料的电化学性能，分析其作为阳极的可行性及适用环境。进行了阻抗、极化曲线和恒电流放电实验并进行了表面表征，计算了在40～120mA/cm²电流密度下连续恒流放电的阳极能量密度。用电子探针显微镜（EPMA）对电极表面形貌进行了研究，用波谱分析仪（WDS）进行表面分析。研究结果表明，合金元素在电池放电过程中会改变阳极的表面特性。6061中合金元素含量对电池阳极材料的性能产生了积极影响，使得合金的表面放电面积变大，放电均匀，更适合作为铝空气电池阳极材料。

Electrochemical properties of Al-6061 and Al-7075 alloys as anode for aluminum air batteries

The electrochemical properties of industrial 6061 aluminum alloy (6061), aviation 7075 aluminum alloy (7075) and pure aluminum as anode materials for aluminum air cell were studied. Electrochemical tests, constant-current discharge experiments and surface characterization were carried out to calculate the anodic energy densities of continuous constant discharge under different current densities of 40—120mA/cm². The surface morphology of the electrode was studied by electron probe microscopy (EPMA), and the surface analysis was performed by using a spectral analyzer (WDS). The results showed that the alloying elements changed the surface characteristics of the battery during discharge. The content of 6061 alloy element has a positive effect on the performance of the battery anode material, making the surface larger and discharge more uniformly , which suggested that 6061 was more suitable to be used as an alloy anode.
