This application relates to a solid-state electrolyte and a preparation method and application thereof, the solid-state electrolyte includes membrane material(s) and electrolyte salt(s), the organic phase of the membrane material(s) includes a three-dimensionally interconnected interface and has a specific interfacial area greater than or equal to 1×10cm/cm, and the electrolyte salt(s) is dissolved in the organic phase. The preparation method of the solid-state electrolyte includes: spraying the polymeric material solution onto the selected receiving surface using electrostatic spinning technique to form a three-dimensional structure, and optionally, at the same time, spraying the dispersion liquid of the inorganic particles onto the selected receiving surface using electrostatic spraying technique, then treating under pressure to give the membrane material(s), and then dropwise adding or spraying the electrolyte salt(s) solution into the membrane material(s) or immersing the thin film in the electrolyte salt(s) solution.
