摘要： A cylindrical secondary battery includes a case, a cathode plate and an anode plate installed in the case, and a separator interposed therebetween, a cap on the case and a cap cover coupled to the cap and having a vent hole, and a one-way valve installed in the vent hole. The one-way valve includes a hollow body portion inserted in the vent hole of the cap cover, gas passing grooves at the outer circumferential surface of the hollow body, an upper flange at the outer circumferential surface of the hollow body, disposed above the cap cover, a lower flange at the outer circumferential surface of the hollow body, disposed under the cap cover, a spring elastically supported between the upper flange and the cap cover, and a fragile portion closing an upper portion of the hollow body. Thus, gas generated during initial charging of the battery can be exhausted by a user through the one-way valve and the one-way valve can also be used as a device for preventing explosion due to the gas generated while using the battery.

摘要： 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.
