The invention belongs to the field of new energy battery materials, and particularly discloses magnetic nanoparticles, a nanofluid electrolyte containing the magnetic nanoparticles and application of the nanofluid electrolyte. The invention mainly discloses an application of magnetic Fe3O4 nanoparticles in preparation of a battery electrolyte and an application of the battery electrolyte containing the magnetic Fe3O4 nanoparticles in a solar flow battery, and creatively finds that the nanoparticles improve the conductivity, peak current density and reversibility of the electrolyte; and the ohmic resistance is reduced. In addition, by utilizing the good conductivity of Fe3O4, the prepared nanoparticles can create an electronic network in a solution, and ion migration is accelerated. Therefore, the photoelectrochemical performance of the electrolyte is improved, and the photocurrent density of the photoelectrode in the nanofluid electrolyte is effectively improved, so that the SFBs have high photovoltage and ge
