Tescan CLARA delivers non-destructive, nanometer-scale insights into separator porosity — enhancing safety and quality control in lithium-ion battery production.
As lithium-ion batteries become thinner, lighter, and more energy-dense, safety margins shrink — and separators carry more responsibility than ever. These porous polymer membranes regulate ion flow while physically isolating electrodes. But if pores are inconsistent or layers too thin, the likelihood of thermal instability and electrical failure increases.
In this study, a polypropylene (PP) separator was examined using Tescan CLARA UHR SEM at low voltage and current — without metal coating — to preserve material integrity. Porosity and fiber thickness were measured via image analysis (MIPAR), providing critical quality metrics for safety-focused battery design.
Tescan CLARA provides high-resolution imaging at low landing energies, making it ideal for sensitive battery materials. Its automated workflows and contrast flexibility allow precise analysis of powder morphology, particle distribution, and surface texture.
