Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A battery pack comprising: a plurality of battery modules, and at least one bulletproof material adhered to the outermost large surface of a battery pack pouch opposite to the surface in contact with another battery pack part, as a separate layer from the battery pack exterior part, wherein the bulletproof material comprises at least one selected from the group consisting of aramid fiber, ultra-high-molecular-weight polyethylene fiber (UHMWPE fiber), and polybenzoxazole fiber (PBO fiber), wherein the bulletproof material has a thickness of 20 mm to 100 mm, wherein the battery pack is adjacent to a duct of an electric vehicle selected from the group consisting of an electric vehicle (EV), a hybrid electric vehicle (HEV) and a plug-in hybrid electric vehicle (PHEV) through which refrigerant flows, the battery pack or the duct is provided with the bulletproof material, and the duct is disposed between the battery pack and the bulletproof material. 2. The battery pack of claim 1 , wherein the battery module comprises at least one of the bulletproof materials.
