    摘要: The present disclosure relates to a secondary battery which is entirely made of a multi-layered metal thin film to increase the overall cross-sectional area, thereby improving a heat generation property, and facilitating bending. In an example, disclosed is a secondary battery comprising: an electrode assembly having a first electrode tab and a second electrode tab exposed to both sides, respectively; a first current collector coupled to the first electrode tab of the electrode assembly; a case accommodating the electrode assembly and the first collector and having both sides opened; a first cap plate sealing an opening of one side of the case; and a first terminal coupled to the first current collector and exposed to the outside of the first cap plate, wherein the first current collector includes a first main plate on which the multi-layered metal thin film is overlapped, and a first sub-plate surrounding both ends of the first main plate in the longitudinal direction, respectively.

    摘要: Provided is a secondary battery having a structure that can reduce a space for the secondary battery. The secondary battery includes: exterior bodies that look a quadrilateral as a whole in a plan view; an electrode body that is housed in the exterior bodies; cutout parts at respective two sides among the sides of the quadrilateral, the two sides being opposite to each other; a cathode terminal disposed in one of the cutout parts; and an anode terminal disposed in another one of the cutout parts.
