Abstract

The effect of mechanical pressing on the electrochemical behavior of a magnesium anode in a chloride-free electrolyte was investigated. Magnesium is a promising material for Mg-air batteries; however, its practical application is limited by surface passivation and intensive localized corrosion. It is established by SEM/EDX analysis that pressing alters surface morphology and increases the oxide fraction. An increase in the anodic activity of pressed magnesium was established by potentiodynamic and potentiostatic studies. After polarization, corrosion products con are identified on the surface. The results indicate that mechanical pressing improves the conditions for anodic dissolution of magnesium and the performance of magnesium anodes in metal-air electrochemical power sources.
