The feasibility of employing aluminum in KOH ethanol solution as a battery anode system is discussed. Weight loss measurement showed that its corrosion rate is low enough to be used in sealed batteries. Through anodic polarization, EIS and galvanostatic discharge, it was found that Al can keep electrochemical activity in a wide potential range in this system, and its discharge mechanism is similar to that of Al in aqueous solution. The discharge potential increases rapidly after a period of time, which may be caused by the discharge products deposited on the electrode surface. (C) 2003 Published by Elsevier B.V.
