Abstract
A cable-type secondary battery is provided. The cable-type secondary battery includes an electrode assembly and a covering capable of surrounding the electrode assembly. The electrode assembly includes a first polarity electrode, a second polarity electrode, and a separator or an electrolyte layer interposed between the two electrodes. Each of the electrodes has an elongated shape and a structure in which an electrode active material is applied to the surface of a current collector whose shape in cross section orthogonal to the lengthwise direction thereof is circular, elliptical or polygonal. The covering includes a thermally conductive cover member as an upper half part and a thermally insulating cover member as a lower half part. The upper half part and the lower half part are divided by a horizontal plane passing the center of the cross section orthogonal to the lengthwise direction of the cable-type secondary battery.
