The process of dry lithium battery separator production line usually includes steps such as melt extrusion, stretching, and subsequent processing. Firstly, the raw materials (such as polyethylene (PE) or polypropylene (PP) particles) are heated to a molten state in an extruder, extruded through a mold, and then cooled and stretched to form the desired film structure.
The main steps of the dry process lithium battery separator production line
Raw material melting and extrusion: The raw material is melted at high temperature and extruded through a screw to form a film.
Cooling: Use cooling rollers or air cooling devices to quickly cool the film material and fix its shape.
Stretching: After cooling the film material, longitudinal and transverse stretching is carried out by mechanical methods to improve the strength, flexibility, and lithium permeability of the film.
Characteristics of dry lithium battery separator production line
High efficiency: Dry process technology usually has high production efficiency and is suitable for large-scale production.
The thickness and strength of the film can be adjusted by changing the stretching ratio.
Environmentally friendly: The dry process does not require a large amount of solvents, reducing environmental pollution.
Application of dry process lithium battery separator production line
Dry process separators are widely used in power batteries, electric vehicle batteries, and other high-performance lithium batteries, and are favored due to their good mechanical properties and lithium permeability.
