COMPLEX CATALYST FOR RECHARGEABLE METAL-AIR BATTERY, METHOD FOR MANUFACTURING THE SAME, AIR ELECTRODE FOR RECHARGEABLE METAL-AIR BATTERY INCLUDING THE SAME, AND METAL-AIR BATTERY

摘要

The present invention relates to a complex catalyst for a metal-air battery, a method for manufacturing the same, a positive electrode for a metal-air battery including the complex catalyst, and a metal battery. More particularly, provided is a complex catalyst for a metal-air battery which is a complex body including a carbonized silk fiber; carbonized carbon black; and a metal. Also, provided is a method for manufacturing a complex catalyst for a metal-air battery, including the steps of: manufacturing a silk fiber solution by dissolving a silk fiber in a solvent; introducing a metal precursor and carbon black in the silk fiber solution; manufacturing a catalyst precursor by agitating the silk fiber solution into which the metal precursor and the carbon black are introduced; and obtaining a catalyst by heat-treating the catalyst precursor. In addition, provided is a positive electrode of a metal-air battery including the catalyst and a metal-air battery. According to the present invention, a reaction between a catalyst and oxygen can be activated and a high durability can be ensured.
