Method for manufacturing of nano-size manganese oxide catalyst for zinc-air battery and Method for manufacturing air electrode for zinc-air battery using the same

摘要

PURPOSE: A manufacturing method of a nano-size manganese oxide catalyst for a zinc-air battery, and a manufacturing method of an air electrode using thereof are provided to manufacture a nano-size manganese oxide for a catalyst layer for of the battery through electro-spinning. CONSTITUTION: A manufacturing method of a nano-size manganese oxide catalyst for a zinc-air battery comprises the following steps: producing a spinning solution by dissolving a fiber producing polymer material, and a manganese oxide precursor; forming a composite nanofiber web by spinning the spinning solution to a current collector; and heat-processing the composite nanofiber web to form a nano-size manganese oxide.
