An electrochemical cell is presented. An anode compartment in the cell contains a sacrificial metal in an amount between about 10 volume percent and about 40 volume percent, based on the volume of the compartment. The sacrificial metal has an oxidation potential less than the oxidation potential of iron. An energy storage device including such an electrochemical cell is also provided. L'invention porte sur une cellule électrochimique. Un compartiment d'anode dans la cellule contient un métal sacrificiel dans une quantité entre environ 10 pour cent en volume et environ 40 pour cent en volume, sur la base du volume du compartiment. Le métal sacrificiel a un potentiel d'oxydation inférieur au potentiel d'oxydation du fer. L'invention porte également sur un dispositif de stockage d'énergie comprenant une telle cellule électrochimique.
