Abstract: A battery cover plate assembly, a single battery, a battery module, a power battery pack, and an electric vehicle are provided. The battery cover plate assembly includes a cover plate, an electrode terminal, a current interrupt structure, and an arc extinguishing portion. The electrode terminal is disposed on the cover plate and includes an electrode inner terminal and an electrode outer terminal. The electrode inner terminal and the electrode outer terminal are electrically connected through the current interrupt structure. The current interrupt structure is capable of disrupting the electrical connection between the electrode inner terminal and the electrode outer terminal under the action of a gas pressure. The arc extinguishing portion is configured to at least reduce an electric arc generated when the current interrupt structure disrupts the electrical connection between the electrode inner terminal and the electrode outer terminal. When the electrical connection between the electrode inner terminal and the electrode outer terminal is disrupted, an arcing effect is generated due to high voltages at positive and negative electrodes of the battery. In this case, the arc extinguishing portion at least reduces the electric arc, so that gas between two disconnected structure members in the battery cover plate assembly is not easy to be broken down, thereby avoiding dangerous accidents such as battery burning and explosion and improving safety performance of the battery.

Abstract: The present disclosure provides a compound explosion-proof valve mounted on a battery cover plate assembly, a cover plate assembly containing the explosion-proof valve, and a battery. The compound explosion-proof valve includes at least two layers of explosion-proof membranes and a flame-retardant structure located between the at least two layers of explosion-proof membranes. When the battery (such as internal temperature or internal pressure) is abnormal, the first layer of explosion-proof membrane is opened; under the action of the flame-retardant structure, the compound explosion-proof valve is in a local oxygen-deficient state, and it is difficult for a high-temperature combustible matter ejected from the battery to ignite under the local oxygen-deficient condition; therefore, the compound explosion-proof valve is capable of reliving pressure in time when the battery is abnormal and effectively isolating external oxygen from entering, thereby preventing occurrence of battery combustion and explosion and avoiding secondary disasters and larger abnormity.
