Background

Lithium cell separation sticky tape on the existing market is various, and for realizing pasting fixed battery effect, lithium cell sticky tape includes: a release layer, a pressure sensitive adhesive layer, and the like. From the material perspective, the lithium battery separation rubber has a rubber system and a polyurethane system. In terms of use principle, the lithium battery separation adhesive tape has a high-resolution system with both soft segments and hard segments. The soft segment serves as a continuous phase to provide flexibility to the system. The hard segment serves as a connection point for the dispersed phase, which is why the lithium battery separator tape can be pulled long and continuous. When the lithium battery is dismantled, the adhesive tape needs to be stretched, and because the cohesion inside the adhesive is far greater than the bonding force between the adhesive and the surface, the surface of the lithium battery and the adhesive surface generate relative displacement, so that the lithium battery is separated from the adhesive. Compared with the traditional viscose glue, the lithium battery separation adhesive tape does not need to pull the battery and does not leave residual glue when the battery is detached, so that the battery is protected, and the battery is prevented from being damaged.

However, in practical use, the above technical scheme still has many disadvantages, for example, the colloid is easily broken in the stretching process, so that the colloid shrinks into a narrow gap between the battery and the battery jar, and the head of the adhesive tape cannot be captured, and the battery is difficult to remove.
