Abstract:
Disclosed herein is a battery module including at least one battery cell constructed in a structure in which an electrode assembly of a cathode/separator/anode structure is mounted in a battery case such that electrode leads of the electrode assembly protrude outside, wherein, when external impacts are directly or indirectly applied to the battery cell, with the result that the electrode leads move toward the electrode assembly of the battery cell, the external impacts are absorbed by the deformation of the electrode leads or the deformation of predetermined regions (‘electrode lead facing parts’) of the module in direct contact with or adjacent to the electrode leads, whereby the occurrence of a short circuit due to the contact between the electrode assembly and the electrode leads is prevented.

Abstract:
Disclosed herein is a plate-shaped secondary battery constructed in a structure in which an electrode assembly of a cathode/separator/anode structure is mounted in a battery case, and the battery case is sealed by thermal welding, wherein the secondary battery has at least one valve (one-way exhaust valve), having a small thickness, mounted at a sealed portion, formed at the outer circumference of an electrode assembly receiving part of the battery case, for allowing internal high-pressure gas to be exhausted out of a battery cell and preventing external gas from being introduced into the battery cell. The secondary battery according to the present invention has the effect of effectively exhausting internal high-pressure gas generated during the abnormal operation of the battery, such as overcharge, out of the battery case, while maintaining the sealability of the battery case, thereby simultaneously improving the efficiency and safety of the battery.

Disclosed herein are an electrode assembly including a plurality of unit cells folded by a continuous separation film wherein the unit cells are arranged on the separation film such that electrode taps of the unit cells face each other, the separation film has openings corresponding to the electrode taps of the unit cells, and the electrode assembly is manufactured by folding the unit cells in the longitudinal (lengthwise) direction of the separation film while the unit cells are disposed such that the electrode taps of the unit cells are inserted into the corresponding openings, and an electrochemical cell, such as a secondary battery, including the same. The electrode assembly according to the present invention is a hybrid type electrode assembly solving the problems of the jelly-roll type electrode assembly and the stacking type electrode assembly. Consequently, when external impacts are applied to the electrode assembly, for example, the electrode assembly falls, it is possible to minimize the occurrence of internal short circuits and thus to improve the safety of the electrode assembly. Furthermore, it is possible to perform the process for impregnating (wetting) the electrolyte into the electrodes in a short time during the assembly of the electrochemical cell.
