Abstract
A method for producing a cathode material for rechargeable lithium-air batteries, which has a cathode catalyst loaded onto carbon, includes: a step of sonicating a mixed solution including a carbon having a specific surface area of 20 to 1,500 m2/g, a surfactant and a solvent, and a step of in situ synthesis of the cathode catalyst by (1) adding a cathode catalyst raw material to the mixed solution and (2) adding a solution containing an oxidant to the mixed solution to cause in situ precipitation of the cathode catalyst onto the carbon, the catalyst having a wire form in which the short axis length is smaller than that of the carbon and is 2 to 50 nm and the long axis length is longer than that of the carbon and is 5 to 200 nm.
