Abstract

This research presents a physical-chemical model of the work processes proceeding in the mechanically rechargeable air-aluminium (AAC) and hydronic (with aluminium anode) electrochemical cells (EC) which allow to create new highly efficient independent power supply sources for aerospace systems and other technical fields. The work reviews two electrolyte types: the alkaline and the neutral salt ones. The model has been developed on the basis of the experimental data obtained by us. The work contains the equations of cathode and anode processes and also of the processes running in the near-electrode areas and electrolytic solution. It offers the stage behavior schemes of the electrode reactions and explains the influence of the discharge rate on the processes of aluminium cathode corrosion.
