Abstract
Method of operating a secondary Metal Air electrochemical cell with a metal anode and an air cathode comprising the steps of (a) at start of a charging session creating in less than 2 seconds an oxygen gas shield on the electrolyte side of the air electrode obstructing ion passage between the bulk of the electrolyte and the air electrode; (b) charging the cell without anodic polarization of the air electrode with the help of (i) electric conductive material placed between the electrolyte side of air electrode and the bulk of electrolyte and (ii) the said oxygen gas shield obstructing passage of ions of the electrolyte between the electrolyte side of air electrode and the bulk of electrolyte; (c) removing the oxygen gas shield at start of a discharging session.
