摘要： An explosion-proof seal plate for an enclosed cell and a production method thereof, whereby current is cut off when the internal pressure of the cell rises, and also the rise of the resistance due to permeation of an electrolyte is limited. Therefore, it is possible to prevent the cell from exploding in the event of the abnormal generation of gas caused by chemical reactions due to overcharge or an erroneous operation and thus protect the device powered by the cell. A thin portion (7a) having a breaking strength of 18 to 24 kg/cm2 is disposed at the center of an upper metallic foil (7) made of aluminum, a thin portion (8a) having a breaking strength of 10 to 13 kg/cm2 is disposed at the center of a lower metallic foil (8) made likewise of aluminum, the diameter (A) of the thin portion (7a) of the upper metallic foil (7) and the diameter (B) of the thin portion (8a) of the lower metallic foil (8) are so set as to satisfy the relation A≥B, these two metallic foils are welded at their center through an insulating gasket (3) and are fitted into a metallic case (4) made of aluminum and having four vent holes, a temperature resistor (5) and a metallic cap (6) having four vent holes (6) are put on the case (4), and the peripheral portion of the metallic case (4) is sealed to obtain a seal plate. In this way, the cell can be reliably exhausted if an excessive amount of gas is generated under the abnormal state of the enclosed cell, and the accidents of the cell such as ignition, explosion, etc., can be prevented.

摘要： The present invention relates to an explosion-proof seal plate for a sealed cell and a production method thereof and aims at providing an explosion-proof seal plate and production method thereof, wherein problems of a risk of explosion of a cell due to an excessive pressure inside the cell caused by abnormal generation of a gas through a chemical reaction accompanying over charge or erroneous use of the cell or damaging of electronic equipment using the cell as the power source are solved, ignition and other accidents can be prevented with a high accuracy by reliably cutting off an electric current when the cell internal pressure increases, and the increase in the resistance due to permeation of an electrolyte can be limited.
In order to accomplish this aim, the present invention provides a thin portion 7a having a breaking strength of 18-24 kg/cm 2 in the central portion of an upper metallic foil 7 made of aluminum and a thin portion 8a having a breaking strength of 10-13 kg/cm 2 in the central portion of a lower metallic foil 8 made of aluminum, wherein the diameter A of the thin portion 7a of the upper metallic foil and the diameter B of the thin portion 8a of the lower metallic foil 8 satisfy the relation A≧B. The two metallic foils are welded at the central portions with an insulating gasket interposed, and encased in a metallic case 4 made of aluminum having 4 vent holes, on top of which a temperature dependent resistor 5 and a metallic cap 6 having 4 vent holes are then placed. A seal plate is obtained by sealing the periphery of the metallic case 4, with which it is possible to prevent accidents such as ignition and explosion of a cell by reliably allowing internal gas to exhaust in the event of generation of a large volume of gas under an abnormal condition of a sealed cell.
