Battery technology

Separator membranes and ceramic tapes with outstanding consistency, quality and efficiency for your fuel cells and batteries

Continuous, consistent, quality

IPCO film casting technology can give you high-quality, stable battery separators in a continuous production.

Our steel belt casting process delivers a homogeneous layer of liquid product onto a steel belt with outstanding consistency of thickness and high level of tolerance.

Control the line speed, temperature distribution, moisture and air speed, giving you greater efficiency, higher production rates and superior quality.

Technology to match your innovation

The rapid transition to electric vehicles requires battery innovation to keep pace. With IPCO technology, we can help in your production of Li-ion batteries, fuel cells and solid state batteries through our high-precision film casting systems.

IPCO has developed a continuous film casting system that dramatically improves the casting process, enabling the production of film products to exceptionally narrow tolerances.

Our steel belts can help you manufacture high-precision products, such as films and ceramic tapes, and the membranes used in Li-Ion batteries, often no more than 10 microns thick.

As well as battery separators and ceramic tape, our casting and drying technologies are used to produce:

These have a huge variety of uses in the electronics, pharmaceutical and medical industries, plus many more.

Precise control over quality

Our solvent-based casting process gives you precise control over line speed, temperature distribution, moisture, and air speed, ensuring optimal membrane formation and drying. Our process maintains a high level of tolerance, guaranteeing the roundness of the drum within 5 µm and precise tolerances for belt thickness and flatness. This leads to efficient continuous production, significantly reducing faults and imperfections in your final product.

Venturi dryer for speed and quality

Our Venturi dryer technology offers a substantial enhancement in product quality and thermal/heat transfer performance compared to traditional dryers. Notably, it contributes to a significant reduction in the length of the drying section, thanks to the availability of a wider belt (up to 2m) and an even distribution of airflow across the width. This leads to an increase in production capacity, with customers achieving double the speed.
