The current interrupt structure includes a sealed chamber configured to fill a gas-producing medium therein. The sealed chamber is configured to make the gas-producing medium to be electrically connected to positive electrodes and negative electrodes of a battery. When a voltage difference between the positive electrodes and negative electrodes of the battery exceeds a rated value, the gas-producing medium is capable of producing gas, to disrupt the electrical connection between the electrode inner terminal and the electrode outer terminal under the action of the pressure of the gas.

  • Patent number: 11177544
    Abstract: A battery device includes a case, a cell disposed within the case, and first and second conductive tabs each electrically connected to the cell and partly enclosed by the case. The first conductive tab has an elastic portion exposed from the case and compressible or stretchable when a force is applied thereto. By having the elastic portions that are elastically deformable, the effects of push or pull resulting from the swelling of the cell and case on the conductive tabs may be reduced. Consequently, damages or breakages of the conductive tabs can be avoided and the safety of battery device may be improved.
