PRODUCTION AND QUALITY ASSURANCE ACROSS THE CELL LIFECYCLE
Evaluation of Lithium-Ion Battery Electrode Porosity

Understanding electrode porosity is key to predicting electrolyte uptake and cycle stability. Large-volume FIB-SEM tomography with Tescan AMBER X 2 delivers statistically meaningful 3D datasets that go beyond conventional 2D cross sections.

  • Analyze void fraction and pore networks in 3D
  • Quantify structural variation across large electrode volumes
  • Correlate porosity with performance, lifespan, and manufacturing quality
See application

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

Insights into the Role of Porosity in Lithium-Ion Battery Electrodes

Porosity is a hidden variable that controls electrolyte flow, charge transport, and cycling behavior. Using Tescan UniTOM HR, researchers can non-destructively map pore distribution and connectivity in electrodes. 

  • Capture full-cell architecture with multi-scale micro-CT
  • Measure pore size and connectivity at sub-micron resolution
  • Link porosity to electrolyte infiltration and ionic conductivity

Investigating Battery Anode Overhang Using X-ray Micro-CT

Anode overhang must remain within strict tolerances to avoid lithium plating and safety risks. Tescan UniTOM XL micro-CT quantifies overhang geometry across assembled cylindrical cells.

  • Visualize jelly roll geometry in full 3D
  • Detect misalignment and asymmetry in electrode placement
  • Map overhang variation to support design and quality assurance
See application
