Our state-of-the-art separator film technology ensures a safe and reliable flow of energy in any lithium-ion battery, powering most things that matter. From day-to-day appliances – be it a laptop, smartwatch, scooter or the smartphone you can’t live without – to batteries enabling the electrification of transport or storing intermittent renewable energy.

The separator film is a key component in a lithium-ion battery. It insulates the battery’s anode and cathode from each other and prevents short circuits and overheating while still allowing the ions to be transported between the electrodes. The quality and design of the separator affects the battery’s capacity, life cycle – and not least its safety.

We pride ourselves in being an enabler of electrification. Producing the finest film, making all the difference.

State-of-the-art manufacturing processes

Our product portfolio contains separator film manufactured through the dry and wet processes, together with coated separators. Our separator films are used in any lithium-ion-battery powering everything from consumer electronics to electric vehicles. With over 20 years of process innovation, we are able to manufacture the finest separator film of 5 micrometers in thickness in mass production, and single ultra-thin coating layer down to 0,2 micrometer.

Dry process
Dry process

During the dry process, polymers are melted and stretched in one direction. This gives high mechanical strength for a low cost, and the separator can be tailored to the customer's specific needs. Dry produced separators have a more uniform pore structure than those manufactured through the wet process.
