摘要： In a sealed power storage device, a device case includes a resin case body with an opening and a resin lid closing the opening. The resin lid is made of electrical insulation resin. A metal terminal member is extended from inside to outside of the device case, penetrating through the resin lid. The resin lid is hermetically molded together with the metal terminal member so that the resin lid is directly joined to the outer peripheral surface of the metal terminal member without interposing another member between the resin lid and the metal terminal member.

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.

摘要： A lid plate and a battery are provided by the present application. The lid plate includes a top lid, a lower plastic and a current collecting disk. The top lid is stacked with the lower plastic. An accommodating space is defined on a side of the lower plastic away from the top lid. Supporting protrusions are provided in the accommodating space. The supporting protrusions are configured to defined a limiting space. The current collecting disk includes the current collecting disk main body and the fuse structure. The fuse structure includes a first part and a second part. The first part is electrically connected to the top lid through the lower plastic, the second part is connected to the current collecting disk main body. The current collecting disk main body is located outside the limiting space and abuts against the supporting protrusions.
