In our latest Aqueous Energy video, Daniel Fischer, Head of Delfort Specialty Paper‘s strategic Battery Separators business unit, explains how the company’s fiber-based separators are tackling the specific challenges aqueous battery developers face, from wettability to dendrite formation.
Watch this video to learn:
- How Delfort’s fiber-based separators are tackling specific problems in aqueous systems, particularly for wet strength and wettability across acidic and alkaline electrolytes.
- Delfort’s customization for a host of paramaters, including thickness (20-150 µm), porosity levels (up to 70%+), and pore size (3-20+ µm)
- How Delfort approaches dendrite mitigation through functionalized separators and multilayer approaches
- How Delfort serves as a scale-up partner, with rapid prototyping capabilities and more than 200+ million square meters of annual production capacity.
If you’re struggling with separator performance in your current cells, this is an interview to watch.
This interview was filmed at the NAATBaat’s Sodium-Zinc workshop in November 2025. More interviews from the event coming soon.
