Metal-air batteries are green power supplies which generate little pollutants and CO2 emission. They are desirable to power electric vehicles and large-scale energy storage systems. Metal-air batteries rely on the electrochemical reactions between a metal and oxygen molecules, therefore requiring an air permeable but liquid impermeable electrode assembly as the air cathode. The air electrode requires a delicate control of its porosity, hydrophobicity, electrical conductivity and most importantly, the catalysts.
The technology is related to the development of a bifunctional catalyst capable of catalysing both oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) for metal-air battery application. The technology provider is seeking for interested industry partners to collaborate for further development of this technology into products as well as technology licensing opportunities.
The invention provides a bifunctional catalysts lanthanum cobalt manganese oxides (LCMO), which is
Potential applications on air electrode systems for electrically rechargeable metal-air batteries (zinc-air, aluminium-air, iron-air), alkaline fuel cells and oxygen electrolyzers.
