| abstract |
The present invention provides a structured adhesive. The structured adhesive comprises: a first adhesive layer, comprising a first adhesive agent, used to achieve adhesion on a target of adhesion; and a magnetic material layer, comprising a magnetic material, provided on the side of the first adhesive layer away from the target of adhesion. When the structured adhesive is used in a secondary battery, a reserved area can be reserved on a current collector to form a terminal tab. The terminal tab in the reserved area provides a strong and secure weld, thereby improving the safety of the secondary battery. |
