  • Lithium secondary battery and method of manufacturing thereof
    Publication number: 20010019796
    Abstract: A lithium secondary battery having a winding-type electrode assembly and a case accommodating the electrode assembly, and a method of manufacturing thereof. In the lithium secondary battery, ion-conductive polymer is contained in at least one of a hollow portion of the electrode assembly and an inner space of the case other than the hollow portion. The hollow portion and/or the inner space of the case of the electrode assembly is filled with ion-conductive polymer which can consume the heat generated in the battery and which is changed into a gel-state by an electrolytic solution, to dissipate the heat generated in the battery. Accordingly, the explosion of the battery can be suppressed, thereby preventing the reliability and safety of the battery from lowering.
