Abstract

An electrochemical battery for production of high outputs and efficiencies with high current densities comprising a plurality of cells, particularly metal-air cells each comprising a consumable electrode, and an air electrode spaced from the consumable electrode with electrolyte disposed in an electrolyte space and current take-off. The consumable electrode has a rod-shape made at least partially of a dense metal, the consumable electrode having a front face constituting a sole working surface projects sealed-off into the electrolyte space. An air electrode is spaced by the smallest distance parallel to the working surface of the consumable electrode, and an adjustable mounting for one of the electrodes maintains the spacing between the electrodes constant. The cells are arranged parallel to one another and connected in series, the air electrode and the consumable electrode of each of the cells being reversed with respect to the consumable electrode and the air electrode of the adjacent cell.
