A battery module includes a battery cell assembly constituted by stacking a plurality of battery cells, an end plate disposed adjacent to one end of the battery cell assembly, and a shock-absorbing member interposed between the one end of the battery cell assembly and the end plate, wherein the shock-absorbing member is woven fabric or non-woven fabric formed of a plurality of fibers.

Battery module

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.

Secondary battery having improved safety

Provided is an electrode assembly, and more particularly, an electrode assembly having a structure wound in a state, in which a plurality of unit cells having a stacking structure is disposed on a long sheet type separation film, and including the unit cells having two or more types of configurations of electrode materials, wherein a separator stacked on the unit cell having a stacking structure has a coating material coated on both sides thereof and the long sheet type separation film has a coating material coated on one side thereof. According to the present invention, an electrode assembly improving processability of preparation of a battery while reducing initial resistance during the preparation of the battery as well as having battery lifetime equivalent to that of a conventional battery and a lithium secondary battery including the electrode assembly may be provided.

Electrode assembly and lithium secondary battery including the same

Provided is a novel structural electric device having improved safety. More particularly, provided is a novel structural electric device devised to resolve several issues regarding heat generation, ignition, and explosion, which may be caused by a sharp needle-shaped object penetrating an electric device.
