Abstract
Provided are a secondary battery, a battery module, and a battery pack, which have improved safety. Particularly, since a bulletproof material is disposed on the inside and/or the outside of an exterior part, even when a conductive needle-shaped member penetrates a secondary battery, heating, burning, discharge of evaporated electrolyte, and electrical contact between the needle-shaped member and an electrode can be prevented, thereby improving safety of the secondary battery, the battery module, and the battery pack.
