In order to separate the positive and negative electrodes of the battery, avoid contact short circuits, and take into account factors such as the passing capacity of electrolyte ions, high-strength thin-film diaphragm materials have become one of the key inner components of power batteries. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and will directly affect indicators such as battery capacity, cycle life and safety of use. In recent years, waste power batteries have gradually become a hot topic in the field of resource recovery because they contain a variety of valuable components. Among all the treatment processes, the discharge and crushing of waste lithium batteries are essential links. After crushing, the components in the lithium battery are gradually dissociated, laying the foundation for subsequent separation and recovery. However, it should be pointed out that the diaphragm in the lithium battery cannot be torn into small pieces during the crushing process due to its high tensile strength, and will still exist in the crushed product in the form of long strips.
