摘要： 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-way exhaust member, 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.

摘要： Disclosed herein is an electrochemical cell constructed in a structure in which a plurality of full cells or bicells, as unit cells, are folded by a separation film formed in the shape of a long sheet, and separators of the unit cells are secured to the separation film by thermal welding. The electrochemical cell according to the present invention has the effect of preventing the electrodes of the stacked electrodes from being separated from the separation film or from being twisted due to external impacts and vibrations, thereby restraining the electrochemical cell from generating heat or catching fire. Furthermore, the structural stability of the electrochemical cell is maintained even when the temperature of the electrochemical cell is increased, or the volume of the electrochemical cell is increased due to the generation of gas.

摘要： Disclosed herein is a safety switch including a tube that is capable of shrinking when exposed to temperatures in excess of a predetermined temperature level (“heat shrinkage tube”), wherein the length of the heat shrinkage tube is changeable to control current conduction, one end of the heat shrinkage tube is fixed, and the other end of the heat shrinkage tube is connected to an electric wire connection part, such that current conduction or current interruption is accomplished by the change in length of the heat shrinkage tube when the heat shrinkage tube is varied due to heat. When a battery or a battery pack is exposed to an abnormal environment, with the result that the temperature of the battery or the battery pack exceeds a predetermined temperature level, the heat shrinkage tube of the safety switch shrinks to directly interrupt external charge current, thereby preventing the further charge of the battery or the battery pack. Furthermore, internal energy accumulated in the battery cell is forcibly consumed, thereby fundamentally preventing the progress of the abnormal operation of the battery or the battery pack. Consequently, the safety of the battery is secured.
