Introduction to the dry single-drawing process of Nickel Hydride No. 5 battery separators
Dry single-drawing process of lithium-ion battery separators
Feeding: PE or PP and additives and other raw materials are pre-treated according to the formula and transported to the extrusion system.
Casting: The pre-treated raw materials are melted and plasticized in the extrusion system and then extruded from the die head. The melt is cast to form a base film with a specific crystal structure.
Heat treatment: The base film is heat-treated to obtain a hard elastic film.
Stretching: The hard elastic film is cold-stretched and hot-stretched to form a nanoporous film.
Slitting: The nanoporous film is cut into finished films according to the customer's specifications.
Wet asynchronous stretching process
Feeding: PE, pore-forming agent and other raw materials are pre-treated according to the formula and transported to the extrusion system.
Casting: The pre-treated raw materials are melted and plasticized in the twin-screw extrusion system and then extruded from the die head. The melt is cast to form a cast thick sheet containing a pore-forming agent.
Longitudinal stretching: The cast thick sheet is longitudinally stretched.
Transverse stretching: The thick film after longitudinal stretching is stretched transversely to obtain a base film containing a pore-forming agent.
Extraction: The base film is extracted by solvent to form a base film without a pore-forming agent.
Forming: The base film without a pore-forming agent is dried and formed to obtain a nanoporous membrane.
Cutting: The nanoporous membrane is cut into finished membranes according to the customer's specifications.
The performance of the diaphragm product is affected by the base material and the manufacturing process. The stability, consistency and safety of the diaphragm have a decisive influence on the discharge rate, energy density, cycle life and safety of lithium-ion batteries.
