摘要： A button cell includes a housing having a metal cell cup and a metal cell top. An electrode winding disposed within the housing is formed from a multi-layer assembly that is wound in a spiral shape about an axis, the multi-layer assembly including a positive electrode formed from a first current collector and a negative electrode formed from a second current collector. A separator is disposed between the electrodes. The first current collector includes a first end section bent so as to extend out of the electrode winding forming an uncoated first flat layer adjacent to the electrode winding. An insulator is positioned (i) between the first flat layer and the first end side of the electrode winding or (ii) between a second flat layer and a second end side of the electrode winding.

摘要： A battery, including a packaging case and a cell assembly, where the packaging case includes a cover, and the cell assembly is provided in the packaging case. The battery further includes a first adapter which is connected to the cover. The cell assembly includes a first tab which protrudes outward from a side of the cell assembly. The first tab and the first adapter are electrically connected, and they are bent toward an outer surface of the cell assembly. In the foregoing battery, a connection structure of a tab has been changed to the outside of the cell assembly by using the first adapter, and the tab and the first adapter are directly bent to the outer surface of the cell assembly, simplifying connection and bending, and reducing operation difficulty.
