CT scanning allows for a detailed, three-dimensional view of a battery's interior, without the need to disassemble it. This is crucial for identifying critical issues that could lead to battery failure or safety concerns including:
- Electrode misalignment
- Anode overhang
- Separator integrity
- Tab weld quality
- Foreign material detection
- Electrolyte distribution
- Internal short circuits
- Cell and module assembly
- Density variations
- Porosity in electrodes
- Structural integrity of casing
- Thermal runaway precursors

The last product you should tear down with a hammer, vice, or a clamp is a battery, because it’s actually a hazard to do that. That’s why CT scanners are an important technology for understanding their inner workings.

21700 lithium-ion battery
Voyager’s dimensioning features allow engineers to measure anode overhang in batteries, as seen here in the LG21700 lithium-ion battery used in the Tesla Model 3 and Model Y.
Lithium-polymer pouch cell
In this lithium-polymer battery, industrial CT reveals considerable layer separation as well as defects with both the tab weld and electrode layers, both of which could lead to thermal runaway.
18650 lithium-ion battery
These 2D views of a lithium-ion battery allow engineers to pinpoint the exact location of foreign material, which could decrease battery efficiency and increase the risk of short circuits.
