UHMWPE Battery Separator Films
Medium and large twin screw extruders for lithium-ion battery separator film, in the dry and the wet process, and for the continuous preparation of cathode and anode paste. USEON mainly supplies the extrusion system and can also provide the complete line solution.
- Separator film extrusion
- Cathode & anode paste
- Output, SAT95 to SAT175
- 300–1,200kg/h
- Screw length
- 52–64L/D
- Separator from one 135 mm extruder
- 50–100million m²/year
Two battery materials, one kind of extruder
Where USEON extruders are applied
Separator film: dry and wet processes are the most common production methods for polymeric membranes. The extrusion and stretching portions of these processes induce porosity and can serve as a means of mechanical strengthening.
Cathode and anode paste: the extruder replaces intermittent production equipment such as the dual planetary dispersing machine, so the paste is prepared automatically and continuously.
Separator film extrusion
USEON has practical experience in both the dry and the wet process.

Machine page: Co-rotating Twin Screw Extruder
Generally one parallel twin screw extruder with a screw diameter of 135 mm and a long L/D reaches a separator output of 50 million to 100 million square metres per year.
Cathode & anode materials compounding
Automatic and continuous paste production, with high automation and excellent sealing.
10GWh
Generally one production line has two sets of USEON parallel co-rotating twin screw extruders, one for the cathode and one for the anode, to meet this annual output.
The process controls the dispersion and uniformity of the active material particles and keeps powder particles and adhesive from layering.
