<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a lithium ion secondary battery, which can sufficiently suppress shift or separation of components of the battery by improving adhesiveness of a separator to an electrode. <P>SOLUTION: The manufacturing method of the lithium ion secondary battery including a separator 110, a positive electrode 120 containing materials of one or more sorts selected from a group composed of materials capable of absorbing and discharging lithium ions as positive electrode active materials and a negative electrode 130 containing materials of one or more sorts selected from a group composed of materials capable of absorbing and discharging lithium ions and metallic lithium as negative electrode active materials includes: a step for allowing a phase transition type gelation agent to exist at least on the surface of one member or more selected from a group composed of the separator, the positive electrode and the negative electrode; a step for obtaining a laminate by laminating the positive electrode, the separator and the negative electrode so that the separator is held between the positive electrode and the negative electrode; and a step for immersing the laminate in an electrolyte. <P>COPYRIGHT: (C)2013,JPO&INPIT |
