The invention discloses aerogel-doped high-temperature-resistant power generation spinning yarn and a preparation method and application thereof.The power generation spinning yarn comprises a nanofiber shell and a yarn core, the nanofiber shell is provided with an axial cavity, the yarn core is located in the axial cavity, and the length of the nanofiber shell is smaller than or equal to that of the yarn core; the nanofiber shell is made of a first dielectric material doped with aerogel nanopowder, and the yarn core comprises a first yarn core wire made of a second dielectric material and a second yarn core wire made of conductive fibers; and the second dielectric material and the conductive fiber are respectively contacted with the inner wall of the axial cavity. According to the preparation method, an electrostatic spinning technology is adopted for preparation, and the fabric is used for manufacturing braided fabrics. The problems that an existing high-temperature protective garment is too heavy and poor i
