    Abstract: A battery cell includes a housing having an inner cavity, a first side wall and a second side wall opposite to each other. The second side wall includes an explosion-proof hole. A first bottom support and a second bottom support are disposed in the inner cavity, support the electrode core, spaced apart from each other, and define a first gas channel. The second side wall support the first bottom support and the second bottom support. The explosion-proof hole communicates with the inner cavity through the first gas channel. A terminal post is disposed on a side wall of the housing other than the second side wall; An explosion-proof valve is mounted on the second side wall, and configured to cover the explosion-proof hole. An electrode core is disposed in the inner cavity, connected to the terminal post, and spaced apart from the explosion-proof hole.

    Abstract: 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.
