The invention belongs to the technical field of a solid-state battery and particularly relates to a preparation method of a solid-state-like battery. The method comprises steps of carrying out freezing ball milling of electrode material powder, conductive agent, plasticizer, binder and lithium salt to form electrode precursor powder (divided into a positive electrode and a negative electrode); freezing and ball-milling the plasticizer, the lithium salt, the binder and inorganic filler to form electrolyte precursor powder, pressing the positive electrode precursor powder into a positive electrode plate, paving the electrolyte precursor powder, pressing the electrolyte precursor powder into a positive electrode/electrolyte complex, paving negative electrode precursor powder on an electrolyteside, and pressing the negative electrode precursor powder into a solid-like battery; and heating the battery, melting the pre-embedded plasticizer, a wetting electrode material and an electrolyte material, and improving wet
