    Abstract: Disclosed herein is a battery cell configured such that an electrode assembly of a cathode/separator/anode stack structure is mounted in a changeable cell case in a state in which the electrode assembly is impregnated with an electrolyte, wherein the electrode assembly and the cell case are curved in the same direction on axial vertical sections thereof in a state in which opposite ends of the electrode assembly and opposite ends of the cell case are directed in the same direction about a middle part of the electrode assembly and a middle part of the cell case. When the battery cell is mounted in an electronic device the external shape of which is curved or in an electronic device configured such that a battery mounting region thereof is curved, the tight contact between the battery cell and the electronic device is achieved, thereby maximizing space utilization and thus providing high efficiency. Also, electronic devices having aesthetically pleasing appearance and various designs satisfying liking of consumers are developed using the battery cell.

    Abstract: Provided is a cathode including a cathode current collector, a cathode tab protruding from the cathode current collector, and an insulation layer coated with an insulating material on the cathode tab, and a secondary battery including the cathode. Since the cathode of the present invention includes an insulation layer on a cathode tab, the present invention may prevent an internal short circuit which may occur due to cell deformation or sharp edges of electrodes, which are formed during cutting of the electrodes in a preparation process of the battery, when the electrodes are stacked, or may prevent a physical short circuit between the cathode and the anode due to shrinkage of a separator in a high-temperature atmosphere. In a case where the cathode is used in a lithium secondary battery, safety and reliability in battery performance may be significantly improved.
