The dry process lithium battery separator production line is a specialized equipment used for producing dry process lithium battery separators. Dry method lithium battery separator is a type of lithium battery separator prepared by dry method, which has higher energy density, better temperature resistance, and lower electrolyte loss compared to traditional wet method preparation.


The dry process lithium battery separator production line usually includes the following main equipment and processes:
1. Material treatment: Process the raw materials required for the diaphragm, such as polypropylene (PP) or polyethylene (PE).
2. Membrane based preparation: The treated raw materials are prepared into a membrane based material through a special process, which is usually made of materials such as polypropylene (PP) or polyethylene (PE).
3. Membrane base stretching: Stretch the membrane base to improve the density and mechanical strength of the membrane.
4. Membrane based pretreatment: Pre treat the stretched membrane base, such as removing static electricity and enhancing surface wettability.
5. Membrane drying: Dry the pre treated membrane substrate to remove moisture and solvents.
6. Membrane based embossing: The dried membrane base is embossed to improve the surface roughness of the separator and enhance the electrochemical performance of lithium batteries.
7. Cutting: Cut the embossed membrane base to obtain a diaphragm that meets the size requirements of the lithium battery.
8. Packaging: Pack the cut diaphragm for future storage and use.
The advantages of the dry process lithium battery separator production line include:
1. Efficient production: The dry process lithium battery separator production line adopts automated control and continuous production, which can significantly improve production efficiency.
2. Stable product quality: Through automated control and precise process parameter adjustment, the dimensional accuracy and quality stability of the diaphragm can be guaranteed.
3. Flexible adaptation: The dry process lithium battery separator production line can be adjusted and modified according to the needs of different models and sizes of lithium batteries to meet different production requirements.
4. Safety and Environmental Protection: The materials and processes used in the dry process lithium battery separator production line meet environmental requirements, ensuring the safety and environmental friendliness of the production process.
