Abstract: A secondary battery includes a cylindrical case; an electrode assembly accommodated in the case and including a first electrode plate, a second electrode plate, and a separator, the electrode assembly being wound such that the first electrode plate is arranged at an outermost side and is in contact with the case; a cap assembly coupled to the case and electrically connected to the second electrode plate; and a first swelling tape attached to an inner surface of the first electrode plate in a state in which the electrode assembly is wound, the first swelling tape having a multi-layer structure. The swelling tape may be applied to a base material finishing portion of the electrode assembly to improve quality distribution of the base material finishing structure due to long-diameter distribution. In addition, a swelling effect may be improved through the multi-layer swelling tape.

Abstract: A cylindrical secondary battery includes: an electrode assembly including a first electrode plate and a second electrode plate; a cylindrical case having a disk-shaped top portion and a side portion extending from the top portion, the cylindrical case accommodating the electrode assembly; a cathode terminal extending through the top portion and insulated therefrom; a first current collector plate electrically connected to the first electrode plate and the cathode terminal; a second current collector plate electrically connected to the second electrode plate and the side portion of the cylindrical case; a cap plate coupled to the side portion and insulated therefrom; and an insulation tape between the top portion of the cylindrical case and the first current collector plate and covering the first current collector plate.

Abstract: An electrolyte for a secondary battery and a lithium secondary battery including the same are disclosed herein. In some embodiments, an electrolyte includes a first electrolyte solution represented by Formula 1 and a second electrolyte solution represented by Formula 2 M1N1X1-n(SO2)??[Formula 1] M2N2X2-m(SO2)??[Formula 2] wherein M1 and M2 are different from each other and each independently an alkali metal, N1 and N2 are each independently at least one metal selected from the group consisting of an alkali metal, a transition metal, and a post-transition metal, X1 and X2 are each independently a halogen element, and n and m are each independently an integer of 1 to 4.

Abstract: A lithium secondary battery including a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and a sulfur dioxide-based inorganic electrolyte solution. The negative electrode includes a negative electrode active material which includes a carbon material having a coating comprising titanium oxide (TiOx, 0<x<2). The titanium oxide improves the wettability of the carbon material negative electrode to the inorganic electrolyte solution and the charge transfer reaction on the surface and minimizes the interfacial resistance of the carbon material/inorganic electrolyte solution, thereby improving the high-rate charge/discharge characteristics.
