Low-keV Imaging of Lithium and SEI
Capture high-resolution images of lithium deposits and fragile SEI layers at landing energies below 1 keV with BrightBeam™ field-free optics, avoiding beam damage and charging artifacts.
TESCAN CLARA for Batteries
Reveal nanoscale details in the most challenging battery materials with TESCAN CLARA SEM for batteries. With the BrightBeam™ electron column, you achieve ultra-high-resolution imaging at low energies, while the field-free design ensures stable results on magnetic and beam-sensitive components. This lets you separate electrode phases, assess SEI integrity, and examine cathode porosity, lithium deposits, and polymer separators with confidence.
- Visualize SEI layers and lithium deposits without damage using low-keV, field-free imaging
- Reveal binder distribution and electrode interfaces with energy- and angle-filtered BSE detection
- Characterize nanoporous cathode morphology at the nanoscale
- Image polymers, lithium, and fragile electrolytes with MultiVac™ variable pressure SEM
- Automate electrode quality control workflows with Essence™ Image Snapper and VisualCoder
- Correlate true-color navigation with SEM imaging via ONCam integration
FOR BATTERY RESEARCH APPLICATIONS
Characterization of Particle Size in Battery Powder
Particle size and morphology in active material powders influence electrode packing, coating uniformity, and long-term stability. With UHR SEM and automation, Tescan CLARA enables fast, reproducible particle size analysis across batches.
- Quantify particle size, shape, and texture in Ni-based powders
- Use automated workflows for consistent quality control
- Optimize powder selection to balance capacity and stability
High-Resolution Analysis of Battery Separators
Separators are critical for both ion transport and safety. Tescan CLARA UHR SEM reveals nanometer-scale pore and fiber structures without conductive coating, preserving the true surface morphology and helping manufacturers control separator quality.- Visualize pores and fiber networks at nanometer resolution
- Assess morphology to ensure mechanical and thermal stability
- Provide quality metrics for consistent production outcomes
AUTOMATED IMAGE ACQUISITION FOR CONSISTENT BATTERY WORKFLOWS
Essence™ Image Snapper automates image collection across multiple regions of interest, ensuring that electrodes, SEI layers, and separators are captured with the same parameters every time. Integrated directly into the Essence GUI, it reduces operator variability and accelerates dataset acquisition for defect detection and quality control. With unattended batch routines, Image Snapper delivers reproducible, high-quality SEM images that standardize battery research and manufacturing inspections.
