PURPOSE: Provided is a stable interfacial structure of secondary battery, which is formed by applying an ion-conductive polymer material on a cathode or anode or separator and adhering them with each other. CONSTITUTION: The secondary battery consists of a cathode(5), an anode(6), a separator(7), and a sheath. In the secondary battery, ion-conductive polymer(8) is applied to the part of cathode, anode, or separator to form a partial adhesion. Also, a part on which adhesion is not formed, provides a space which enables liquid electrolyte to uniformly penetrate. The separator consists of a single film or a composite film of polyethylene, polypropylene, or polyvinylidene fluoride. The separator has porosity of 40-80%, and thickness of 5-50 micrometer. |
