1. A method for manufacturing a battery or a fuel cell electrode, the method comprising:

  • forming a film by applying a composition comprising a precursor of a composite metal oxide onto a base material,wherein the precursor of the composite metal oxide comprises;

    a first precursor comprising one to three first metals selected among lanthanum (La), strontium (St), gadolinium (Gd), samarium (Sm), barium (Ba), and bismuth (Bi); and

    a second precursor comprising one to three second metals selected among manganese (Mn), cobalt (CO), iron (Fe), nicel (Ni), and calcium (Ca);

    wherein the base material is an electrolyte membrane; and

    manufacturing an electrode by firing the film,wherein in the firing, the film is sintered while the precursor of the composite metal oxide undergoes a chemical transformation to form a composite metal oxide.
