The invention discloses a manufacturing method of an all solid state power lithium ion battery. The manufacturing method comprises the steps of dissolving an anode active material, a conductive agent,an adhesive and a polymer electrolyte in a solvent, so as to prepare an anode sizing agent, applying the anode sizing agent to an anode current collector, performing thermal treatment and rolling treatment so as to obtain an anode piece; then dissolving a cathode material, a conductive agent, an adhesive and a polymer electrolyte in a solvent, so as to prepare a cathode sizing agent, applying thecathode sizing agent to a cathode current collector, and performing thermal treatment and rolling treatment so as to obtain a cathode piece; dissolving a polymer electrolyte, a filler and lithium salt in a solvent, so as to prepare an electrolyte solution; applying the electrolyte solution to the surface of the anode piece or the cathode piece, and performing thermal treatment to obtain an anodepiece or a cathode piece with an electrolyte layer; and finally, assembling the anode piece and the cathode piece in a winding or superposing manner, so as to prepare the all solid state lithium ion battery. The all solid state lithium battery prepared by the method has the advantages of lower interface resistance, higher energy density, high security and the like.
