ABSTRACT:
Method and apparatus for electrochemically producing electricity. Ion contivity is established between an oxygen-reducing electrode, and adjacent ion pervious insulating membrane, a paste which has flow characteristics comprising particles of an oxidizable metal and a liquid electrolyte, and an inert electrode in physical contact with said paste. In said paste, the metal particles are in an amount constituting from 60% up to the critical pigment volume composition. The metal paste is moved from a first reservoir through the electrochemical battery wherein it is oxidized to the corresponding metal oxide paste and passed to a second reservoir. The battery may be recharged by reversing the movement and electrolyzing, or by reducing the metal oxide paste in an external circuit.
