CT for batteries | Quality control and R&D

Invisible but critical stakes

Batteries are now at the heart of electric mobility, stationary energy storage and the development of new technologies such as solid-state batteries. Their performance, lifespan and safety depend directly on internal phenomena that are often impossible to observe with conventional inspection methods.

Non-destructive battery analysis

X-ray CT offers a non-destructive approach to inspecting complex, dense or costly components, regardless of their geometry. It enables inspection processes that are faster, safer and more complete than conventional methods.

Explore our CT systems: micro-CT, nano-CT, high-energy CT, custom-made.

CT to meet the challenges of the battery industry

Develop higher-performing batteries

Increase energy density while ensuring safety and lifespan.

Detect hidden defects

Metal contamination, overhang, delamination or assembly defects can appear well before a problem is detected electrically.

Industrialize new generations

Move quickly from lab cell to large-scale production.

Understand aging

Observe degradation mechanisms before they affect performance.

Why CT in the battery industry?Detect earlier, qualify faster, produce with more confidence

A battery’s critical defects are often invisible to conventional testing. CT gives you a complete view of the internal structure to improve quality, reduce risk and speed up development.

Detect defects before they become a safety risk by identifying metal contamination, delamination or assembly defects.
Reduce production scrap by identifying anomalies earlier in the manufacturing process.
Qualify new chemistries and architectures before industrialization.
Speed up failure analysis without destroying the evidence.
Reduce destructive test campaigns while keeping complete data.
Improve process repeatability through a better understanding of recurring defects.

Unlike electrical tests or 2D inspections, CT lets you visualize the entire internal structure of a battery with no disassembly or destruction. It provides usable 3D data to understand defects, qualify processes and make decisions faster.
