Abstract: A battery cover assembly includes a cover plate, an electrode inner terminal and an electrode outer terminal. The electrode inner terminal is electrically connected to the electrode outer terminal through a current interrupt structure disposed on the cover plate. 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.
