摘要： Disclosed is a secondary battery. The secondary battery includes a battery can serving as a positive electrode terminal or a negative electrode terminal of the secondary battery, an electrically conductive substrate provided at an outer portion of the battery can, and a nonconductive film interposed between the battery can and the electrically conductive substrate in order to insulate the electrically conductive substrate from the battery can, wherein the electrically conductive substrate is electrically connected to an electrode terminal having polarity opposite to that of the battery can. Safety of the secondary battery is ensured even if the secondary battery is subject to external parameters, such as penetration of a sharp tool (e.g. a nail or a drill tip), pressing force of a tool (e.g. a nipper), external impact, and exposure to the high temperature.
