Provided is a method for preparing a polypyrrole nanometer wire-graphene composite material. Pyrrole monomer and graphene powder are added in prepared disodium hydrogen phosphate lithium perchlorate aqueous solution with certain concentration according to certain proportion, even suspension liquid is obtained after ultrasonic dispersion, an experiment is carried out in a three-electrode system controlled by an electrochemical workstation, an electrochemical method is adopted, and the polypyrrole nanometer wire-graphene composite material is obtained through polymerization on an electric conduction substrate. The method is simple in process, short in time, controllable in operation procedure and low in cost. The composite material is high in conductivity rate, capable of serving as electrode materials to be applied to a fuel battery, capable of being applied to supercapacitors, lithium batteries, sensors and the like.
