Technology

The main elements of the system include a metal-air cell, a tank of mineral oil and electrolyte, and a separate tank of water. Pumps and pipes move liquids between these three parts. The device displaces corrosive electrolyte from the anode surface by pumping oil into the cell. In comparison to other mechanical corrosion mitigation methods, this oil displacement method increases volumetric energy density by 15%. Additionally, a liquid that has a different density than the electrolyte, is immiscible in the electrolyte, non-conducting, inviscid, and nonreactive with the other system components could replace the oil in this system.
