Technical Field

[0001] The utility model belongs to the technical field of termination tapes, in particular to a termination tape for lithium batteries. Background Art

[0002] Termination tape is an important material in the production process of lithium batteries and plays a key role in battery assembly. Its main function is to protect lithium batteries from short circuits and prevent overcharging and over-discharging of the batteries. In the production of lithium batteries, termination tape is generally used to fix positive and negative electrodes and separators. After the battery is assembled, the termination tape will firmly bond the positive and negative electrodes and separators together to form a complete internal structure of the battery;

[0003] When the lithium battery termination tape is used, after one end of the tape is peeled off, in order to facilitate finding the joint again, it is usually extended for a certain distance and opened at a certain angle. However, the opened tape is prone to adhere to dust and impurities, which affects the reuse. Therefore, a lithium battery termination tape is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a lithium battery termination tape. When the tape is installed, the top plate can be moved by moving the top sleeve, so that tapes with different inner diameters can be fixed, thereby improving the flexibility of use. At the same time, during the movement of the second slider, the pressure block can be driven to move, thereby flattening the edge of the unfolded and exposed tape, effectively reducing dust and impurities adhering to the extended tape, facilitating reuse, and solving the existing technical problems.
