摘要： A current collector, a battery cover plate, and a battery structure are provided. The current collector includes a first connection portion and a second connection portion. The first connection portion is connected to an electrode post holder, and the first connection portion and the second connection portion are connected through a bending-resistant portion. The battery cover plate includes the above current collector, an electrode post, and a top cover plate. The electrode post body penetrates the top cover plate to be connected to a terminal. The terminal and the current collector are disposed on opposite sides of the top cover plate, and the first connection portion of the current collector is connected to the electrode post.

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 facing 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 passes through the lower plastic and is electrically connected to the top lid, 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. It can avoid a situation that the battery is shaken by setting the supporting protrusions, thereby causing the current collecting disk main body to press the fuse structure, so that an installation space of the fuse structure is reduced. The lid plate can effectively solve a problem that adhesion may occur even if the fuse structure has been fused, so that the current collecting disk main body is still in a conductive state, ensuring safety in use of the battery.
