Description

Technical Field

[0001] The utility model relates to the technical field related to production and transmission of battery diaphragms, and in particular to a production and transmission mechanism for polyimide lithium-ion battery diaphragms. Background Art

[0002] In the structure of lithium batteries, the diaphragm is one of the key inner components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and directly affects the battery's capacity, cycle and safety performance. A diaphragm with excellent performance plays an important role in improving the comprehensive performance of the battery. The main function of the lithium battery diaphragm is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and short-circuiting. In addition, it also has the function of allowing electrolyte ions to pass through. During the transportation of the lithium battery diaphragm, the diaphragm is guided by the action of rollers, but the rollers lack a structure to limit and guide the diaphragm, which causes the lithium battery diaphragm to gather from the edge to the middle, causing wrinkles on the lithium battery diaphragm on the roller, which affects the subsequent cutting and use of the diaphragm.

[0003] To this end, we propose a polyimide lithium-ion battery separator production transmission mechanism to solve the above problems. Utility Model Content
