High-Resolution CT for Battery Packs, Cells, and Components

Nel PreTech Corporation provides non-destructive industrial CT scanning services tailored for lithium-ion batteries, solid-state batteries, and fuel cells.

Battery OEMs and suppliers can identify internal defects, ensure quality standards, and accelerate R&D with precision 3D data.

Unlike traditional X-ray imaging or destructive testing, industrial CT scanning services deliver complete volumetric data—capturing internal and external geometries with micrometer-level accuracy. Whether you're testing pouch cells, cylindrical cells, or battery modules, industrial CT reveals the critical details without opening or altering the part.

Key Capabilities:

• Internal defect detection (porosity, delamination, foreign material)
• Dimensional metrology (electrode spacing, casing thickness, weld quality)
• Failure/root-cause analysis
• Process validation and quality control
• Cycle testing support with 3D voxel views
• Assembly verification and reverse engineering

R&D Engineering:

• Visualize internal architectures without destructive teardown
  
• Analyze material interfaces and electrolyte distribution
• Optimize electrode stacking, separator alignment, and current collector placement

Production & Quality Assurance:

• Detect critical internal defects:
• Void formation
• Weld cracks
  
• Internal shorts
• Separator folding
• Dry spots or inclusions (foreign material)
• Validate spot welds, laser welds, and tab placements with high-resolution CT
• Correlate 3D data with process parameters to improve yields and reduce scrap

Failure Analysis / Root-Cause Investigation:

• Localize short circuits, swelling, electrolyte leakage, and thermal events
• Compare failed cells to control samples in full 3D
• Incorporate CT scanning into your cycle testing to:
  
• Correlate performance drop to physical changes
  
• Compare brand-new cells to post-cycle cells to monitor degradation
  
• Detect electrode particle displacement or dendrite growth
  
• Generate actionable insights to mitigate risk and prevent recurrence
  

Industrial CT technology accommodates a wide range of battery types, including:

• Cylindrical cells (e.g., 18650, 21700)
  
• Pouch cells
• Prismatic cells
  
• Battery packs and modules
  
• Solid-state and prototype formats
  

Scan subcomponents, such as separators, jelly rolls, housings, current collectors, and fasteners for assembly analysis or metrology.
