Metal-air rechargeable battery needs bifunctional air-electrode catalytic materials, which involve effective oxygen reduction/evolution at the air electrode at the discharge/charge process. We have developed new air-electrode catalysts using carbon nanoparticles synthesized by the solution plasma process with various organic solutions, such as benzene and toluene. The developed carbon nanoparticles show an excellent bifunctional oxygen reduction/evolution activity, being much superior to that of the conventional carbon material: acetylene black.
