[0002] The diaphragm is a thin film used to separate the positive and negative electrodes during the electrolytic reaction to prevent energy loss due to direct reaction in the electrolytic cell. In the structure of lithium batteries, the diaphragm is one of the key internal 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. Diaphragms with excellent performance play an important role in improving the overall performance of the battery. The main diaphragm material products include single-layer PP, single-layer PE, PP+ceramic coating, PE+ceramic coating, double-layer PP / PE, double-layer PP / PP and three-layer PP / PE / PP, etc.

[0003] During the processing of the diaphragm, the ceramic barrier needs to be applied to the PE material, so it is applied with the help of a diaphragm coating machine. However, when adding materials to the existing coating machine, since its feeding trough is built-in, it is necessary to wait until the machine stops before adding materials, which greatly reduces the work efficiency. For this reason, we propose a diaphragm coating machine that is easy to add materials to solve the above problems. Utility Model Content
