Abstract
Various embodiments of the present invention relate to a secondary battery and a manufacturing method therefor, and the objective of the present invention is to provide a secondary battery having improved safety and a manufacturing method therefor, the secondary battery preventing an electrode assembly from moving inside a laminate exterior material during a drop shock and/or collision, thereby suppressing a voltage drop, a heating phenomenon, and/or ignition and the like caused by a small short between a cathode plate and an anode plate. To this end, disclosed in various embodiments of the present invention are a secondary battery and a manufacturing method therefor, the battery comprising: an electrode assembly including a first electrode plate, a second electrode plate, and a separator interposed between the first electrode plate and the second electrode plate; a pouch exterior case for encompassing the electrode assembly; and an adhesive dispensed in a dot array form on a surface of the pouch exterior case toward the electrode assembly.
