ADVANCED METAL AIR ELECTROCHEMICAL CELL AND METHOD OF FABRICATION

An advanced metal-air-electrochemical-cell includes a cathode with cathode material providing enhanced oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Examples of metal-air-electrochemical-cells are rechargeable metal-air batteries and metal-air fuel-cells. Metal air electrochemical cells can be based on a variety of metal fuels such as: aluminum, germanium, calcium, iron, lithium, magnesium, potassium, sodium, tin, and zinc. In various examples, a rechargeable metal-air-battery includes a configuration that allows an aftermarket replacement of electrolyte in the metal-air-battery thereby refreshing the metal-air battery to provide more discharge/charge cycles and extending the usable life of the metal-air battery. A metal-air-fuel-cell includes anode slurry material including metal particles and electrolyte that can be refreshed, in addition to refreshing the electrolyte, to enable refueling of the metal-air-fuel-cell.
