"The application of Al and Al alloy anodes in Al–air batteries requires the electrodes to have minimal passivation so that dissolution can occur with ease. However, this depassivation leads to the spontaneous degradation of aluminum. In addition, the self-corrosion reaction of aluminum with release of hydrogen causes fuel loss in alkaline media. Thus, adding inhibitors to the electrolytes becomes one of the most effective methods to relieve these problems. The primary inhibition mechanism of corrosion inhibitors is utilizing the adsorption of inhibitor molecules on the aluminum surface to effectively lower the corrosion reaction."

I found this idea interesting about Corrosion inhibitor additive for extending the life of aluminium air battery. The electrolyte additive will slow down the corrosion of the aluminium.
