Unlike other batteries, which contain environmentally harmful materials, our technology is based on the use of clean and abundant oxygen and zinc to generate an electric current. Our patented air electrode allows oxygen to enter the cell while providing a stable three-phase boundary for the oxygen reduction (discharge) and oxygen evolution (charge) reactions. The discharge and charge reactions are enhanced through careful selection and
positioning of our patented catalyst materials and electrolyte within the three phase boundary. During discharge, oxygen is reduced to form hydroxyl ions, which migrate through the electrolyte to the zinc anode. The zinc anode oxidizes and releases electrons. During charge, hydroxyl ions are converted to oxygen at the air electrode, releasing electrons, which are consumed at the anode as the zinc oxide is reduced to form zinc.
The unique combination of our patented bi-functional air-electrode, catalysts and electrolytes has enabled us to overcome many of the obstacles associated with developing rechargeable metal-air batteries. These breakthroughs ensure that metal-air technology will soon be available to introduce a new era in the development of mobile applications.
