摘要:  研究纯铝在KOH 乙醇溶液中的电化学行为,腐蚀失重、极化曲线、EIS和恒电流放电实验表明,该体系纯铝的腐蚀速率极小,因而有可能应用于密闭电池,并可在相当宽的电位范围内保持一定的活性.放电的终止可能是由于放电产物在电极表面堆积引起的.

Abstract: The feasibility of employing aluminum in KOH ethanol solution as a battery anode system was discussed. Weight loss measurement showed that the corrosion rate of Al is low enough to be used in sealed batteries. Through the measurements done by anodic polarization, EIS and galvanostatic discharge, it was found that A1 is electrochemical active in a wide potential range in this system, and its discharge mechanism is similar to that of A1 in aqueous solution. The discharge potential increased rapidly after a period of time, which might be caused by the discharge products depositing on the electrode surface.
