CABLE-TYPE RECHARGEABLE BATTERY |
摘要 |
The present invention relates to a cable-type secondary battery comprising a polymer electrolyte having a first electrolyte layer comprising a mixture of a first polymer and a first organic electrolyte solution in a weight ratio of 50:50 and 80:20; and a second electrolyte layer formed on at least one surface of the first electrolyte layer and comprising a mixture of a second polymer and a second organic electrolyte solution in a weight ratio of 20:80 and 50:50. Since the multiple-layered polymer electrode film of the present invention exhibits good characteristics in terms of both mechanical property and ionic conductivity, the cable-type secondary battery comprising the same according to the present invention has superior battery performances and flexibility, as well as good strength for withstanding external impact. |
