Gauging Solutions for Energy Storage Materials

Separator films are crucial components in batteries. These thin, permeable plastic films prevent the anode and cathode from coming into physical contact. It is essential that these films are accurately produced with the correct porosity and desired mechanical properties to ensure safety and enable proper ionic movement within the battery cell.

Nordson's gauging solutions allow precise measurement of critical parameters of battery separator films, ensuring the production of high-quality components that meet safety and performance requirements. Our gauging solutions enable reliable and consistent measurement of basis weight, thickness, density, and oil content, providing a comprehensive understanding of film quality. For instance, our systems can accurately measure the oil content in PE battery film at various stages of the production process, from the wet cast film, through the biaxial stretching, to the final film.

In addition, Nordson's solutions can measure the ceramic coating applied to the separator film.

Production processes for high-performance lithium-ion batteries (LiB) used in mobile devices, electric (EV/HV) vehicles, and stationary energy storage systems must adhere to very high-quality standards to ensure maximum performance, utmost safety, and the longest battery lifespan.

Nordson offers measurement solutions for LiB component production that go beyond conventional gauging methods. They provide a complete end-to-end gauging system, from basis weight measurement of anode and cathode coatings to final product thickness measurement in the roll press line.

These solutions offer greater process visibility and control, allowing you to exceed market demand for outstanding quality and performance while realizing bottom-line advantages.
