Tescan solutions for Batteries:

Failure Analysis and Characterization in Lithium-ion Batteries

Heating of Lithium-ion Battery and Visualization of Electrolyte Dynamics

Thermal effects play a key role in failure mechanisms. Using Tescan’s in-situ workflows, electrolyte dynamics can be visualized under heating to reveal degradation pathways.

Observe gas formation and electrolyte distribution during heating
Track microstructural and chemical changes in real time
Support safety testing and predictive modeling of thermal effects

Electrode Particle Degradation Characterization

Electrode particle degradation drives capacity fade and internal resistance growth. Tescan AMBER X 2 with ToF-SIMS and Raman spectroscopy enables full structural and chemical analysis of degradation processes.

Visualize exfoliation and fracturing in anodes and cathodes
Map lithium trapping and chemical inhomogeneity in 3D
Correlate microstructural and chemical data for targeted improvements

See application

Spectral CT in the World of Electronics: Moving Toward Failure-free Devices

As electronics become smaller and more integrated, ensuring internal quality without disassembly is increasingly essential. Tescan’s spectral micro-CT reveals internal defects and material inconsistencies in wearables and PCBs, non-destructively, in full 3D.

Separate copper, solder, and polymers in dense PCB assemblies
Detect battery delamination inside smart rings without opening the device
Identify high-Z elements like tungsten and gold via K-edge spectral imaging

See application
