Roller and Surface Technology for Sensitive Thin Films in Battery Manufacturing

Presented by Bill Stahl, INOMETA, GmbH

In the battery manufacturing the proper handling of material is critical through all areas of battery manufacturing. These areas consist of foil/film production; calendaring; coating/laminating; slitting and winding. We will discuss the importance of having the right solutions for all these areas.

In the area of rollers, we will look at importance of the choice of materials whether it is aluminum or carbon fiber as well as using the smallest manufacturing tolerances. We will discuss how these have a direct effect on maintaining low roller deformation under load, low starting torque and mass inertia. Regarding coatings, we will focus on the topics of traction, cut resistance low surface roughness and why these are important to consider in the manufacturing process.

With 40 years of roller building experience, these principles have already been proven in a wide variety of film manufacturing. Our goal will be to show how these topics will bring many benefits to all manufacturing process to help reduce waste, reduced maintenance down time and increase production volume and quality.

The film production phase of battery manufacturing can have a direct impact on output quality, volume and profitability of the final product. Because of the complex process of producing film, which includes calendaring, coating, laminating, slitting and winding, ensuring quality and consistency during film production is critical.

This session will focus on the impact that rollers used to produce film for battery manufacturing has on the outcome of the final product. It will look at the importance of the choice of materials such as aluminum or carbon fiber and why manufacturing tolerances are critical and explain how these have a direct effect on maintaining low roller deformation under load, low starting torque and mass inertia. In the coating phase, we will review the impact of traction, cut resistance, low surface roughness and why these are important to consider.

After 40 years of building rollers for a wide variety of high and low tolerance film manufacturing processes, including film for battery production, we have encountered many of these issues and helped provide solutions for the process. Our goal is to share what we have learned and demonstrate how your manufacturing can reduce waste, maintenance down time and increase production volume and quality.
