1. A second-generation high-temperature superconducting (HTS) strip, comprising: a superconducting strip body and a stabilizing layer arranged on at least one side of the superconducting strip body; wherein the stabilizing layer is a copper-graphene composite film, and a mass fraction of graphene in the stabilizing layer is in a range from 0.1% to 1%;
wherein the graphene is dispersed in a copper layer of the stabilizing layer, or the graphene is discontinuously distributed in the form of a layer;
wherein the stabilizing layer is deposited on one side or two opposite sides of the superconducting strip body by a copper-graphene double-target co-sputtering vapor deposition method through a sputter coating process;
wherein a coating temperature does not exceed 200° C. in the sputter coating process.
