Abstract
A secondary battery having improved safety and a manufacturing method thereof, which can suppress a voltage drop, heat generation, and/or ignition due to a minute short between a positive electrode plate and a negative electrode plate by preventing or substantially preventing an electrode assembly from moving within a laminate exterior case due to drop impact and/or collision are provided. A secondary battery includes: an electrode assembly including a first electrode plate, a second electrode plate, and a separator between the first electrode plate and the second electrode plate; a pouch exterior case including a planar long side region and a short side region to surround the electrode assembly; and adhesives in a dot array configuration at an outermost portion of the electrode assembly facing the planar long side region of the pouch exterior case.
