    Abstract: A bipolar electrode is provided to include: a collector; a positive electrode active material layer disposed on one surface of the collector; and a negative electrode active material layer disposed on the other surface of the collector. The quotient of the volume resistance of the collector and that of the positive and negative electrode active material layers is between 10 -3 and 10 4 . The bipolar electrode is provided to further include a current distribution relaxation layer having a volume resistivity lower than that of either the positive electrode active material layer or the negative electrode active material layer. At least one active material layer having a volume resistivity larger than that of the current distribution relaxation layer is disposed between the current distribution relaxation layer and the collector.

    Abstract: In the state where a positive electrode (18) and a separator (21) are held in a case, the value of the ratio of the tensile elongation in a first direction of the separator to the tensile elongation in the first direction of a positive electrode substrate (22) is from 4 to 68. In the same state, the value of the ratio of the tensile elongation in a second direction of the separator to the tensile elongation in the second direction of the positive electrode substrate is from 4 to 68. The value of the ratio of the thickness of a heat-resistant layer (31) to the thickness of the positive electrode substrate is from 0.25 to 0.70. The proportion by mass of heat-resistant particles contained in the heat-resistant layer is from 30 to 99% by mass of the heat-resistant layer.

    Abstract: Provided is a cable-type secondary battery including an electrode assembly and a cover member surrounding the electrode assembly, the electrode assembly including first and second electrodes of an elongated shape and a separator or an electrolyte interposed between the first and second electrodes, each electrode including a current collector having a cross section of a circular, asymmetrical oval or polygonal shape perpendicular to the lengthwise direction thereof and an electrode active material applied onto the surface of the current collector, wherein the cover member has at least partially a predetermined concavo-convex pattern in the direction of the electrode assembly.
    The cover member of a concavo-convex pattern may improve the flexibility of the cable-type secondary battery. When the cover member is applied to an electrode active material pattern layer, the flexibility of the cable-type secondary battery may be further improved.
