The negative electrode of this battery is made of graphite and other materials, and the positive electrode is made of lithium iron phosphate, lithium cobalt oxide, lithium titanate, etc. Due to its high energy, high battery voltage, wide operating temperature range, long storage life and other advantages, it has been widely used in military and civilian small electrical appliances.

[0003] With the continuous promotion of new energy vehicles, lithium battery technology has developed rapidly, and the production of lithium batteries has also increased dramatically. However, the service life of lithium batteries is limited, so the number of retired lithium batteries has also increased. How to deal with retired lithium batteries has become a new hot topic.

[0004] The existing lithium batteries are all semi-enclosed by polyester films on the outside to protect the lithium batteries. The polyester films are resistant to high temperatures, have good tensile strength and moisture resistance, and play an important role in fixing the core package to avoid wear and reliably insulating it from the outer shell. They also have a high recycling value to ensure the normal use of lithium batteries. However, when recycling lithium batteries, the existing recycling method is to crush the battery core and the polyester film as a whole and then screen them. On the one hand, this method cannot recycle and reuse the polyester film as a whole. On the other hand, when various materials in the core package mixed with the polyester film powder are recycled on a large scale, the recovery accuracy of each component is reduced. Utility Model Content

At this time, the conveyor belt 1 stops conveying, and the external drive device drives the recovery device 4 to move close to the polyester film on the battery pack to absorb the polyester film. Then the recovery device 4 moves and lifts along the second direction b, and moves away from the battery pack with the polyester film in the third direction c, while releasing the polyester film to separate the polyester film covering the battery pack. Finally, the battery pack is transferred by the grasping device 5 to complete the separation and obtain a complete polyester film for collection.

[0038] The term "and / or" in this article is merely a description of the association relationship of associated objects, identifying three possible relationships. For example, A and / or B is specifically understood as: A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.
