Abstract
The present disclosure provides a bonding structure, a bonding method, an insulating adhesive tape, and a battery. The insulating adhesive tape includes a first bonding area and a second bonding area disposed at intervals, and a non-bonding area disposed between the first bonding area and the second bonding area. The first bonding area is configured to bond a cell, the second bonding area is configured to bond a welding area formed by a tab of the cell and a current collector, and the non-bonding area is configured to correspond to a bending area of the tab.
Claims20
An bonding structure comprising:
- one or more cells, each of the one or more cells being connected with at least one bendable tab;
- a current collector welded to one side of the at least one bendable tab away from the one or more cells and defining a welding area on the current collector;
- and
- one or more insulating adhesive tapes, each of the one or more insulating adhesive tape having a first bonding area and a second bonding area disposed at intervals, and a non-bonding area disposed between the first bonding area and the second bonding area, the first bonding area being bonded to the one or more cells, the second bonding area being bonded to the welding area, and the non-bonding area corresponding to a bending area of the tab;
- wherein, in a first direction, the tab has a first side and a second side disposed opposite to each other, each of the one or more insulating adhesive tapes has a first redundant bonding area extending out of the first side, and a second redundant bonding area extending out of the second side, both the first redundant bonding area and the second redundant bonding area are bonded to the current collector, a length of each of the one or more insulating adhesive tapes is L, a width of the tab is W, and a sum of widths of the first redundant bonding area and the second redundant bonding area is X1, wherein L≥W+X1.
An insulating adhesive tape comprising a first bonding area and a second bonding area disposed at intervals, and a non-bonding area disposed between the first bonding area and the second bonding area, wherein the first bonding area is configured to bond one or more cells, the second bonding area is configured to bond a welding area formed by a tab of each of the one or more cells and a current collector, and the non-bonding area is configured to correspond to a bending area of the tab.
