because paper is energizing
We are giving wings to sustainable energy storage solutions. Our IonPort® fiber-based separators ensure seamless ion flow between anode and cathode in batteries and supercapacitors. Designed for longevity and endurance, it enables extra charging cycles, extending lifetime. Restoring energy – again and again.
We will be at the Future Battery Forum from November 5th - 6th 2024 in Berlin Germany. We look forward to welcoming you at booth J06!

IonPort® - empowering tomorrow's potential
As the world increasingly shifts toward CO2-free energy and electric mobility, the demand for efficient, reliable, and sustainable energy storage solutions has never been greater. Central to this evolution is the role of advanced battery technology. Due to its natural abundance fiber-based battery separators have become a material of choice for its application for supercapacitors and secondary batteries. A solution that is poised to empower the next generation of energy storage systems.
what is a battery separator?
A battery separator is a microporous layer placed between the positively charged anode and negatively charged cathode of a battery or supercapacitor. During charge and discharge, separators permit the passage of ions between cathode and anode and prevents short circuits.
The quality of an adequate battery separator plays a significant role for the energy and power densities, battery life-cylce and the prevention of an electrical short circuit.
