摘要: A 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 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.
