Electrochemical battery. [mechanically rechargeable, 10 kW, 400 kWh, 48 V, 208A]

Patent ·
OSTI ID:5260184
An electrochemical battery for production of high outputs and efficiencies with high current densities comprises a plurality of cells, particularly metal-air cells, each comprising a consumable electrode, 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 and is made at least partially of a dense metal. The consumable electrode has a front face constituting a sole working surface and 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. 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. 2 figures, 1 table.
