This invention discloses a cell composite, its preparation method, and an all-solid-state battery, belonging to the field of solid-state batteries. The preparation method includes: fabricating a positive and negative electrode sheet; preparing a non-Newtonian imprinted high-fluorine electrolyte substrate; preparing a solid electrolyte precursor suspension; spraying the solid electrolyte precursor suspension onto the surface of the non-Newtonian imprinted high-fluorine electrolyte substrate using a high-speed spraying device, and then heating at 60°C for 5-10 minutes to fully fluorinate the surface of the non-Newtonian imprinted high-fluorine electrolyte substrate surface with the solid electrolyte precursor suspension; imprinting the electrolyte layer coated on the non-Newtonian imprinted high-fluorine electrolyte substrate onto the positive electrode sheet using high-speed imprinting, then stacking the negative electrode sheet onto the surface of the imprinted electrolyte layer, and performing isostatic hot pressing to solidify the electrolyte layer and form the cell composite. Simultaneously, the cell composite prepared in the above steps improves the composite quality and efficiency between the electrolyte layer and the electrode sheet, and reduces interfacial impedance.
