    Abstract: A battery includes a shell, a core and a protection component received in the shell. The core includes a first electrode tab connected to a first current collector and a second electrode tab connected to a second current collector of the core. The protection component includes two insulating layers and a conducting layer disposed between two insulating layers. The conducting layer defines a first end electrically connected to the first electrode tab and a second end configured as a free end, and an outmost current collector of the core is configured by the second current collector.

    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.
