The experimental results showed that the corrosion rate in this system is so low that it can meet the condition to be used in sealed batteries. It was also found that aluminum keeps active to some extent in a wide potential range and its discharge potential is near to that in aqueous solution. The sharp increase of discharge potential, which led to the end of discharge, was probably caused by the deposition of discharge products on aluminum surface.
