    摘要: Disclosed herein is a secondary battery having a mechanical connection sensor, as a safety device, fixed to the outer surface of a prismatic or pouch-shaped battery cell while the mechanical connection sensor is set to OFF. The mechanical connection sensor is connected in series with a resistor having a predetermined resistance value and with a cathode and an anode of the battery cell. When the battery cell swells to a critical value or more due to the abnormal operation of the battery cell, the mechanical connection sensor is turned ON, and therefore, the mechanical connection sensor conducts with the result that the electrical energy of the battery cell is consumed at the resistor. In the secondary battery having the safety device according to the present invention, when the battery swells due to the abnormal response of the battery, energy accumulated in the battery is forcibly consumed, unlike a conventional battery that merely intercepts the current. As a result, the continuous occurrence of the abnormal response is fundamentally prevented, and therefore, more rapid process is possible with excellent pressure sensitivity. Consequently, the safety of the battery is improved.

    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.

    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.
